I am sorry to hear that you are experiencing this issue.
We've only seen that error a few times, and reinstalling the framework resolved the issue.
Please also try to install our latest internal build version of the framework. You can download it from here.
Please calibrate your IE according to this article.
Let me know if this helps.
I am using Telerik Testing Framework for test automation, but sometimes (actually quite often) the NavigateTo() wont open the url.
I am using IE8.
can you also tell the supported Chorme and firefox versions
thanks in advance.
We support Firefox 4.0 till the latest, as well as Chrome 14 till the latest version.
If the issue with the navigate step still persists please send us the Trace logs.
Hope to hear from you soon.
