RC2 to RC3 Upgrade-An Error Has Occured! Messages

[qualtrough]

SMF Version: SMF 1.1 RC3
Finally got my 1.1 RC2 forum the way I wanted it when I got the upgrade message. I just installed the RC3 upgrade by installing the new files over the old ones, and the upgrade window showed that everything was installed successfully. I noticed that the ad mod had disappeared, so I went to the Packages area and I saw this message:

An Error Has Occurred! Unable to load the 'browse' template. 

I get similar messages when I try to access Permissions, Calendar, etc. Since everything was supposed to have been loaded successfully I have no idea where to start on this problem. Any suggestions appreciated.

Try re-uploading the sources and themes, then check your error log

I will try that and report back. Thank you!

I was using Dreamweaver so I went and uncloaked the files on the server and reinstalled the new upgrade files. This time there were no files that were unwritten and that seems to have done the trick. Thanks again.
