Bug maybe or am i stupid?

I just got Inf 2.86 of the PCzone mag's cover disk, and well i was grinning from ear to ear I have to praise the Inf team and i think we should build a church or somin similar to honour them but i think i may have noticed a small bug, i can't pick up any weapons of the ground even if I throw away all my other weapons incase you need to make room. I did remove the older cversions of inf before installing the lastest version. I also backed up my Inf_loadout.ini, Infiltrationuser.ini and InfiltrationBotTeams.ini files. would overwriting the new 2.86 .ini file with the old 2.85 .ini file cause this problem? Please help me if ya can.

hehe i found out what the problem was It was me copying the old inf key settings file from inf 2.85 to inf 2.86 this in turn messed up the bindings for infiltration, although they seemed to be alright in the gui. So it is me being El stupidrado
