I am using this software on XP, but now I switched to Windows 7 and it is working, but when I try to save a project, the application doesn't save for some reason. What is the problem?
The application is not launched with full rights meaning that it cannot save to whatever directory you wish. In this case, all you need to do is to run the application with administrator rights. Right click the shortcut and select Run As Administrator and you will be able to save.
