The error.log is just a simple text file that does not affect any procedure once it has been created or deleted. The errors that are still included in the error log indicate some inconsistencies with the PBF setup information.
However, as you can post now we should get back to your issue once it will probably reappear.
It is always a bit tricky to use usernames that contain spaces or special characters for PBF.
That is why on the other forum we recommend to avoid that or to change the name.
In any case jim-parker should work on this forum. Of course you need to change the Forum information in the PBF setup-screen to forums.triplea-game.org .
