First, is you cog on the right way (some are not asymmetric)? Second, never run a fixed wheel without properly tightening the cog/lockring, the slipping/tightening may have been the hub threads getting hosed. Buy the tools and install properly or bring to LBS to make sure it is a) not ruined. b) installed properly.
