re-installing mx simulator?

[CRASH]

I purchased mx simulator a while ago but I recently upgraded from windows 7 32 bit to windows 8 64 bit. how do I re-install the game without purchasing it again? I did do a dual boot while installing windows 8 so I can still access the windows 7 profile but I just cant figure out how to transfer my mx simulator files.

Each one is on its own partition right? Look on the next drive letter after C: for the original partition.

If you need a new installer link send me the email address you ordered with in an email or PM.
