Alright, just to update you on what's happening in my DAW.
Those of you who suggested that there might have been something wrong with the registry were actually right. I forgot to mention it, but I changed the drive letters for my hard drives after I installed Sonar so I wouldn't have any problems when opening projects containing files from here and there. So it's a proper noob mistake, Sonar got a little confused, I got very confused and I am sorry for having passed that confusion along to you guys as well
Anyways, tech support have been very quick and helpful and I have fixed the issue by removing every thread of Sonar X2, registry and all, and reinstalled it with my hard drives having the correct drive letters.
So cheers to tech support and thanks to everyone for your suggestions and help
I suppose you can have your thread back now Jlien X
