ThinMick has covered the basics of the issue with your saved scenes but it sounds like you aren’t completely clear on the installation process and content libraries and there are some complications of that which may be affecting your saved scenes.
The first question is whether you have reinstalled all of the content used by your saved scenes. Saved scenes stored as .DAZ need to access the information stored in the /DATA sub-folder of your DAZ Content folder, and need the same information to be in /DATA as when they were created.
From the screen capture you have three DAZ content libraries, the first being C:\Documents and Settings. If this first folder isn’t meant to be a content folder, and it would be a little odd for it to be one, then it might cause you issues and you would be advised to remove it from the list of content folders. I believe C:/Archivos de Programa/DAZ is the Spanish version of C:/Program Files/DAZ and depending on your version of Windows this may cause an issue, it certainly isn’t an advisable location for content. If you have any content actually installed under it, then I would advise dragging them to your content library on H:/ and removing it as both a DAZ and a Poser content library. Your H/:Programas/Base/DAZ 3D/Studio/My Library content library should be fine and given the issues with the other two locations specified I would advise dragging all other content into it.
I understand i can find M4 and other products under poser librarys at the content, but my main issue is that my content still isnt appearing under Daz Studio Formats
Whether an item appears under DAZ Studio Formats or Poser Formats depends on the contents of that individual item. Poser format files: .CR2, .PP2, .PZ2 etc will go into the Poser Runtime folders, DAZ format files DAZ, DUF, DS* (where * is any of several different characters) will go into the DAZ content folders. It’s perfectly possible for an item to install and only place content into Poser Format, in fact most items prior to Genesis will place the majority of their files into Poser Format.
When you install content you should specify the content folder, and DAZ content should then load into the DAZ Content Folder, with Poser content dropping down into the Runtime folder below that. If you can’t find content after installing it, check in the neighbouring folders, the most common issue is files being installed one level too low, or one level too high. If they’re in the wrong place, just drag and drop them into the right folder. Some items are sensitive about being installed in the first content folder listed, the Gen 4 figures like M4 being one of them, so if H/:Programas/Base/DAZ 3D/Studio/My Library is your current main folder and the one you installed M4 into then you need to rearrange things so it is the first content folder listed instead of the last.
If you look at the M4 page http://www.daz3d.com/shop/michael-4-base-male-3d-model/ you’ll find the What’s Included tab lists the included files as Michael 4 (.CR2 & .OBJ), P5+ Material Presets (.PZ2), P6+ Material Presets (.MC6), DAZ Studio Material Presets (.DS). What this means is that under Poser Formats you should find the M4 CR2 installed in the figures folder (and in H:/<>My Library/Runtime/Libraries/Characters/(M4 folder) on your disk), while the PZ2s will be under Poses (and in My Library/Runtime/Poses/(M4 Folder)) and the .MC6s will be in Materials (and in My Library/Runtime/Materials/(M4 Folder)). The only files that should be under DAZ Studio Formats are the DAZ Material Presets. There may also be an Update M4 batch file you need to run, with a shortcut to it placed on desktop which you need to run before being able to use the figure (I can’t remember if that is needed for M4, or just for K4 and H4 and the M4 morph packs).
