I get the following error when trying to run dotTrace against an ASP.net

debug server.

exePath must be specified when not running inside a stand alone exe

I have gotten it to work prior, but have received this error multiiple times before it finally worked and now again with no luck getting it to work.  I am trying to trace a page with a login redirect.

The specific line in the asp.net exception is:

System.Configuration.Configuration cfg = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

Thanks!
