Yes, I agree. It seems your situation has become confused so if you can start over, do so. Also, you might want to take the time to watch a few brief videos we have on https://www.axcrypt.net/ .
There are no special gotchas for uninstall / reinstall of AxCrypt. If you uninstall, the files remain encrypted, but you can’t open then because you don’t have AxCrypt. Reinstall just installs the software. You still need to know the password.
