ToUrl method not working after Upgrade

I am using FireFox 4 and IE 9. Behavior exists with both browsers. I installed a trial version of Test Complete on my laptop at home and ran my project and the behavior goes away.(scripts run successfully) Also, had another developer here run the sripts on his machine and the script runs fine as well. Issue either seems to be with my machine here at work, or with the install on my machine. Note I did some load testing with this install earlier this summer and it worked great. I am just sort of at a loss as to what to do in terms of troubleshooting.



Again, browser fires up but nothing else. Do you have any recommendations ? Any advice or direction would be greatly appreciated
