I just spent 45 minutes troubleshooting this, so I thought I would share. The developers of this application made the idiotic decision to place the user name in a directory name where the binaries for the program exists.
Forget that we have an %APPDATA% designed for this purpose and the developers are currently using the CURRENT_USER hive in the registry for most of the data anyways. Why this directory even exists boggles my mind.
Anyways, if it happens to you. Here is the solution:
1. Close all instances PL/SQL Developer.
2. Go to where the program is installed (e.g. "C:\Program Files\PLSQL Developer")
3. In that directory change to the sub-directory "Preferences".
4. You should see another directory with your old user name, change that directory to your new user name.
