I have installed Carrara 5...but when I try to use it, all I am getting is "unknown error when opening ____" The blank includes "new","object","sky"...everything I try to do brings up this message. I am on a PC with Windows XP SP2, with Pentium 4 CPU 2.60 GHz and 3.62 GB of RAM. Can't seem to find out what my graphics card is. I have tried repairing Carrara, but it didn't help. I don't know if it would help uninstalling, then re-installing. The program will not even bring up the toolbars. Please help!
