Recycle bin error

I am trying to view my recycling bin but am getting the following error.

Sorry, something went wrong 
An error occurred during the compilation of the requested file, or one of its dependencies. Could not write to output file 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\5d64f311\fa0df837\App_Web_recyclebin.aspx.9c9699a8.qmr82ugx.dll' -- 'The directory name is invalid. '

Correlation ID: ef78199c-686a-807c-35e3-3b407ba32f85 

Note, it was working fine last week. Has anyone else encountered this error? What can I do to fix it?
