Andre, why are you not using the latest version of FsP? If it's a serial code issue, you will need to email Dan...if you bought it directly from him.

Thats because I don't want it to install in the C partition on my SSD.
However when I DO install a newer version in C then it runs ok. This means that my older version won't work anymore.
Oh well I can fly again with FsP, but basicly it must be that I decide where I install whatever prg.
