Folder lock 7.0.6 cannot open vault, software hangs

I am having an issue with Folder lock 7.0.6. The program opens fine and lets me get to the screen to open a locker just fine, but every time I try to open the locker the software just hangs up. I can kill the application using task manager (windows XP-latest build), but the process folder lock remains open. Then I cannot shut windows down, and my only recourse is to turn off the power to get a reboot.
I have tried everything I can think of to fix the issue, so I am desperately seeking the wise counsel of the fine members of this site willing to share their expertise.
Thanks in advance for any help that anybody can provide.
I thought that the problem might be Comodo firewall, but I gave all the folder lock related pieces that I could find total access rights.
