Problems with BSQUARE bFAX Pro 5.0 V5.00.0000

Hi,

I have installed the BSQUARE bFAX Pro 5.0 V5.00.000 software into my NEC MobilePro 900C (windows ce.net 4.2). I am not very sure whether it will work with MP900C because when I close the program the following message appeared on the screen:

Fatal Application Error

Application bFax50.exe has performed an illegal operation and will be shut down. If the problem persists, contact the program vendor.

Program: bFax50.exe
Exception: 0xC0000005
Address:03F853E4

Any one here has used the program for MP900c? May I know what is the problem? And how do I solve it?

Any one here please suggest the fax software that will run in MP900c (windows ce.net 4.2) and where do I find it?

Thank you very much.
