Accounts randomly reset????

[Unit0094]

I have mount and blade non steam and recently reinstalled a 2nd version of mount and blade on steam (so I could get the napoleonic wars DLC) and ever since I reinstalled the steam version when I go to play Nord Invasion mod which is on my non steam version, all my accounts have been reset like the serial key from steam had somehow overwritten my non steam version. Bloody steam........

Could anyone please help me in this situation????
