Did you try verifying local files for the game?
Can you start a new game and save/load?
If the bug report tool isn't working, you can email supportdos@larian.com, with a description of the problem and the report.zip file generated by the
D:OS support tool.
For the forum problem, did you try logging out, deleting any Larian.com cookies, restarting the browser (maybe even reboot) and logging back in? Can you try in a different browser, or from a different computer?
