I recently did new installs of FS2004 to clear up some scenery issues. Yesterday I installed FSP on an FS install on a portable drive, today on my PC and I get the message that the key is invalid. It's the same key I used yesterday with no such issues. If the code is invalid, it should be indicated as such, not inform you after you've started your flight. FSP is money well spent, I have it for both FSX and FS2004, I expect stuff like this from a crappy program, but not something as extraordinary as FSP.
