Hi,

For your information, the login problem is fixed.  IIS caches files in this temporary directory, and when the power went out, one or more of the files it would pull was corrupted. So tech support just suggested deleting the directory so that IIS would refresh those temporary files.  Now we are able to login iMIS.

See the ASI Tech Support responded to our issue that fixed this error:

This error is referencing Crystal Reports. Have you recently installed Crystal Reports on your iMIS application server? iMIS 15 installs the Crystal runtime during the core components install and if you later installed another version of Crystal on this server, it may be conflicting with the one iMIS installed.

If that is not the case and no other version of Crystal Reports is installed on this server, then what I'd suggest doing next is to delete the temporary .NET files for iMIS and restart IIS. The temp folder for iMIS .NET is located under

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

and will be named the same name as your virtual directory (or application name) in IIS. In this case, it should be called iMIS_prod. Go ahead and make a backup copy of this folder, then delete the iMIS_prod folder under C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files folder and then restart IIS. And then test going back to http://mail/iMIS_prod and see if you still get the error

Hope this helps!
