Qt Creator - problem loading project

[Ferric]

Hello,

For some reason I get the following error message when I try to build my project, the strange thing is it was working yesterday! (nothing has been changed).

[Error Message:]

Starting C:\Documents and Settings\Owner\Desktop\Qt Programs\LoaderV5\release\LoaderV5.exe...

The process could not be started!

[End of error message]

I have also noticed when I load my project, the header files and .cpp files are no longer in their own folders when being displayed in the "projects" box, (they were in their own folders yesterday)

Does anyone know where my problem lies?

Many Thanks

Well, I just restarted my computer again, and now it works. The "Forms", "Headers" and "Sources" files are also now visible. I have no idea what the variable was that was making things not work...
