Mesh Grabber Update
Currently i have the Mesh Grabber Bundle which is in V3, and only the base program is visible within DS and not the other tools. DIM has not given any updates to the latest version and uninstalling and reinstalling doesn't seem to work either as it still installs V3. If anybody knows where or if i can update the program your input would be very welcome.

So you installed threough DIM, and OKed the security prompt? What are you expecting to see and not seeing?
There're three plugins you need to install: Mesh Grabber, Mesh Grabber Editor and Mesh Grabber Rotation Add-on. Then check if they're enabled in About Installed Plugins...
You also have to close and restart Daz Studio if it was open when you installed the plugins.
