If you were a donator and are now using the Desura build and want to keep your profile data it will need to be moved to a new folder location here:

C:\Users\**username**\AppData\Local\VirtualStore\Program Files (x86)\Lunar Flight Beta\LunarFlight_Data\ProfileData

Lunar Flight creates files in  the games folder and Windows does not allow this when the game is located in program files. Windows maps any files created by an application to this location.

Note: This is specifically for Windows 7 users but may apply to Vista users.
