I'm very sorry you're experiencing these issues.
We've released a patch today (to Steam for now) that should resolve this exact issue.
However, it might take some time for Humble Bundle and GOG to update the DRM-free versions that's downloadable on their sites.
That said, we've uploaded/sent them the patch, but for now you will have to wait until they've actually released the new files on their end.
As soon as the patch has been uploaded to their servers, you should hopefully be able to get rid of this issue.Go to the full post
