Log in troubles and error messages on this site come from one of these 3 reasons.
1. You have two accounts with the same email address. One of these accounts will have to be deleted. Send me a PM and I will get remove one of the accounts.
2. Your user name or password have something other than a simple letter or number in them.
This site doesn't like things like *%$#, or umlauts or non-english language symbols in user names and passwords. If your UN or PW has something like ths, and you are having trouble, you should start a new account, send me a PM (click on my avatar) and I will get you credit for your previous number of Forum posts.
3.
