V41 - HP-41CX Hepax problems

[Artur - Brasil]

Hi,
Does anybody use the V41 emulator, version 9D, and has the HEPAX.MOD module installed on virtual machine?
When I "plug" the module, the emulator will turn on, but after the first OFF, it won't get on again. So, I have to close the window (it is installed on a Windows 7 Pro machine, SP 1) to get it working up I turn it off.

Any help, please?
