Unable to Login as Admin Via Forum(SOLVED)

Hi,

I recently changed the link to my website, as soon as i submitted that, i was logged out immediately.
I attempted to log in with my administrative account and it was unsuccessful. Stating that the information was not correct.
So i tried the utilities route, password etc and had no luck with that. I don't think it's anything suspicious other than a glitch perhaps in regards to myself changing the forum address. I did a forum back up also (may of been a wrong move?), and it restored it back to the old template, address etc. Again, no joy with the login. I have also tried to access with the back up names so that if ever a problem with the main account, i had one or two to fall back on. It is the same issue with those too.

If someone of greater knowledge could help me please then i would greatly appreciate it as i was in the process of doing the mighty launch

I shall send the link to the person that can help.

After the process above, the issue was fixed by doing another forum back up, a clean up of the history and cookies etc.
Giving it some time before attempting to access the website again. On accessing i then attempted the "Forgot Password" option and all went smoothly from there.
