Whoa, new development in the case. Realtek has just released version 6.15
of the driver and it looks like it fixes the problem on my machine

The driver was released 28/07 so its very new, and after that update i
can use groupwise messenger again.

I hope it fixes the problem for u guys as well. Let me hear if it does

I found the driver here:
