I have not used virtual girls in a few years and now it is called i-stripper.
My problem is that when I installed the new version all my girls are now greyed out. I moved the models that i backed up into the proper folder but they are still all greyed out. I now have a very slow broadband connection and it would take forever to download them all again.

Does anyone know why they are not showing as they should?

Is that what the "Rebuild Collection" button in advanced settings is used for, I've never had to move my collection but that sounds familiar. And make sure you pointed the software to the right directory which sounds like you may have already done.
