Rich or Art, Has there been any progress on a solution for this error problem? I am have the same problem with my main computer at home which is running XP 32 professional service pack 3. i have tried the same things that RossF has with the same results. I have tried loading the program on a memory stick with the same results. It works fine on the computer controlling the lathe which is running on Vista but I would like to be able to get this up and running at my desk
Any Help would be appreciated.
Jon

Sorry, I don't have a clue as why LT will not work on your pc.

Rich, Just to update you on the situation with my computer. It seems to be an OpenGL issue with ATI cards. The files will not open from the pull down menu in LT but can be opened from the original location folder by using open with command.
Thanks for your help
Jon
