How to fix corrupted TruClient Web - IE script

Hi There,

I am using LR VuGen v12.50 TruClient Web - IE protocol to create a script. After running the script a few iterations with the TruClient Browser, the browser was hung, I had to kill the TcWebIELauncher.exe process to stop the script running. But then when I re-launched the TruClient Browser it says 'Load failed' and nothing was displayed in the browser. I closed the TruClient Browser and ran the script on VuGen itself, the following error is returned.

The script seems to be corrupted. Does anyone know how to fix this by looking at this error? I really don't want to rescipt the transaction as it's a lengthy and complicated transaction.

Thanks!
