I'll look into it, thank you very much!
Regarding shameful noobish questions...
I'm trying to install a new plugin but every time this message appears: "Cannot create file C

Program Files\Autodesk\3ds Max 2010/UI\Icons\Thumbs.db - access denied" and the installation stops. I tried turning off Kaspersky, changing folder settings from read-only but to no avail. I didn't find anything on this matter in google.
The strange thing is that I can't seem to tick off the read-only box in Icons folder settings. No matter what I do it always ticks itself on again!
