[Ifeffit] kind of solve the porblem...

Hi everyone (again), I kind of solve the problem. I can't save in C: but it lets me save in external devices. I got some help and this person said the problem might be something about security of vista and 7, something about libraries (I don't know that much) the program uses that security doesn't let me save on C: If someone has had a seemed problem have an idea of how to solve please comment...
