I'm not sure I can be of much more help under the circumstances, however, I might suggest that you do these things.
1- Visit http://www.visiontek.com . Click on Tek Support on the left, and then on Vision Tek Forum. I believe the forum you need is Legacy Vision TekProducts. Register, if you are not a member, and then start a new thread about your problem.
2- Failing that, contact VisionTek's technical support at [email="support@visiontek.com"]support@visiontek.com[/email] and e-mail them a description of your problem.
Either of the above may provide the assistance you require. Good Luck and please post the results here for the benefit of all our forum readers/members.
