Richmathews; You -may- have a valid concern there. E-on has a few tricks they use to prevent piracy; one of them involves the installer and the CD. Warez kiddies have reported this same behavior with ripped copies of Vue; no stability and constant, random crashes. If this was a valid copy of VuePro it should: (1) Have been in a rigid box that opens from the side. (2) Have a 461 page manual, with the liscencing agreement on page 461 (3) Have the 3 CD's in a cardboard, triple fold protector as large as the manual that has a shortcut reference printed on it, among other things, and (4) A registration card and a rigid envelopes of Vue scene postcards. If all that was not there, then you may have a problem. If it is there, then contact E-on. There have been some defective CD's, and they should replace them if they are. You might want to test the install on another computer first, though. A flakey CDDVD combo drive can cause that kind of problem due to buffer overrun on installation. So can a memory stick that is in the process of failing.
