At first the program was starting fine and giving me -1 on execution. However then I changed some of its settings to incorrect ones and closed the program. Since then everytime I open the program it displays an error which says "ISO Producer has encountered a problem and needs to close. We are sorry for the inconcenience". The Problem report contains this information

"Error Signature
AppName: isoproducer.exe AppVer: 1.1.0.1 ModName: unknown
ModVer: 0.0.0.0 Offset: 000000000"

This happens to Popstation4, the newest version downloaded of dl.gj.net. The computer has too drives, a CD-RW Samsung SW-252S, and a DVD+RW Phillips. I tried uninstalling the drivers for the CD drive and unzipping the program. Also tried redownloading the actual PopStation.

Any solutions would be highly appreciated.
