MQ series: error in thread \"0\"

I had installed MQ series adapter for enterpise server, but when I tried to run in in test mode or enable it, it gives me an error message:
Error in thread “0”. The message gave me no idea on how or where to identify the problem. Does anyone know where the problem could be?

I had the same problem, I resolve by patching MQ Series with the following patch from IBM:
MA88 Classes for MQ Series.
