Unable to record with Chrome/FF but possible with IE

Hello

My problem is a weird one.

I cannot record any test steps with Chrome or Firefox on my website. Telerik Test Studio was perfectly capably to record tests of any kind back in December 2015. Now acts in this way:

• I click the record test button and choose Chrome or FF.
• Browser opens and I am greeted with the "navigate Url" page
• I enter the chosen URL and get redirected to said website. This step is recorded perfectly.
• Now the recording window is displayed in the bottom and the page is loaded.
• Whenever I now take a step, I see the black box in the top mid screen which states which step I did and what gets recorded. But no test steps are actually being recorded.

I don't know what is the cause of this, as this was working befor and is still working with IE.
