blocking my Lathem Payclock program.

I was using 2009 Internet Security and everything worked fine.  When I upgraded to 2011 Internet Security my program quit working.  I tried allowing the folder it was in ect. and the program opens, asks for my password and then I get a windows error saying the program failed.

 

If I unload 2011 my Lathem Payclock program works fine again.

 

This payclock program has to poll a timecard terminal that is plugged into my computer via USB

 

Any ideas?

 

Thanks

Jules
