Can't open log and config folder from within Olympus / Can't update

OS: Windows 10
Olympus: 21.01.28.11
Celeste: v1.4.0.0 / 1.3.1.2 (Tested with both versions)

I got a fresh installation from game banana. (olympus_cea7e.exe).

1. Open Olympus
2. "New version avalible. Install?"
3. Install
4. Wait
5. Click "Restart"
6. Olympus restarts, and it (in the options menu) it shows it has updated itself to the latest version
7. Manually restart (close & open it again) Olympus
8. Olympus is now the version it was before the update

When I try to open the "Log and Config" folder from within the options menu, I just get a small red "ERROR" on the corner.

This may or may not be related to the fact that my windows username folder ( %USERNAME% ) contains spaces, and accents (`á` for example)

Any help would be much apreciated
