Open the folder C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files and delete everything you see in it. It may show warnings like admin permissions required etc. Just choose to continue deleting.

If you are not able to delete something, stop IIS, delete it and then start it again.
