Connectors problem to generate NC Drill Files in Altium - access violation error in module OUT_Drill.dll
Does the problem happen with any connector that has through holes? 

Then this looks like a bug in Altium. You'll need to contact Altium support to get help. 

Does the problem only happen with this particular footprint? 

Then it's probably a bug in the footprint or library file. Quickest solution is probably rebuild the footprint yourself in a new library file.
