I installed V 2.0 and it works great. But when I close the program and then restart it I keep getting an error " cannot open file c:\users\username\appdata\roaming\movienizer\scripts\original_progam.pas System cannot find this path"
when you click OK, the next error "cannot set language" comes up and the program crashes.

Has anybody else experienced this, and what can I do?

This means that you installed Movienizer as a different user (administrator?). You have to install it under the same user account that you use to run it.
