thanks for the fast response! 
I can't get the IR.exe to run, if I start it manually I get an error message "Failed to initialize Infrared Remote Hardware", windows does not report any conflicting or missing drivers. Mediaportal says no problems detected in the hauppauge remote tab. The mediaportal component hcwhelper.exe crashes everytime I exit mediaportal, could this have something to do with my remote not working as it should?
Tried cleaning the system from all hauppauge drivers and apps using hcwclear and then reinstalling the drivers for the nova t-500 and the ir32 but the problem still exists.
Any ideas?
edit: attached the logs if someone would care to take a look.
