Linking box M&B to Taleworlds account

[Loerzys]

I have 4 M&B games: basic M&B, Warband both from GOG.com and WFaS (2009) and WFaS (2011) both in box edition. I succeded to link only Warband and WFaS (2011). How can I link basic M&B from GOG.com and basic WFaS(2009)? When I try to link my WFaS(2009) activation key which is in the box, Taleworlds site tells me that key is invalid.
