invalid mex file problem.

1
I am the first time user of psychtoolbox. When I try to run PsychHID('NumberDevices?'), it gave me following error message:

"??? Invalid MEX-file 'C:\Matlab
Functions\Psychtoolbox\PsychBasic\MatlabWindowsFilesR2007a\PsychHID.mexw32': The specified
module could not be found."

I am running a 32 Matlab on a 64 windows 7 machine.
I tried UpdatePsychtoolbox, which run good. Anyone could please give me any suggestion?

Thanks

Type KbCheck(-1) and you will understand. Btw. PsychHID doesn't support all functions of the os/x PsychHID, only the subset that makes sense on Windows. Also most stuff is only lightly tested, because i don't have suitable hardware for testing and feedback since release was almost non-existent. Prepare for street bumps...
