Update: The log in issue on the forums has now been fixed.
There seems to be small glitch with the username database in vBulletin which is preventing certain users to log in properly to our system.
Over the last few days I have received a few messages from users having this problem. I'd like to ask you give me a couple of days until I can investigate further on this and give it a proper solution. If you are being affected, please mail me to julio AT techspot.com with your details and I will get back to you as soon as possible.
