My user profile for windows became corrupted in some way and I couldn't get into the PC. In desperation I choose to reinstall windows. I assumed it would save my personal data but it would remove any apps. So when I reinstalled Thunderbird I had hoped to be able to link to my local folders. However, I can't. I've tried a few of the suggestions I've found on Mozilla forums but they're not working for me. Any suggestions or help would be much appreciated.
