Can't log in from Mozilla Firefox?

Hi! My computer was broke for a while and just got it running again.
Requested new password last night to log in and see what's new and all I can get is this message
"The specified password activation key was incorrect or has expired. Please re-request a new password. If that fails, contact the forum administrator at [email protected].". I tried several times, requesting new passwords --- and got the same message every time.
That was using Firefox browser.
I just opened IE and tried again and was able to request a new password and log in. Changed the temporary password to a more memorable one and opened Firefox and tried to log in from there --- STILL won't let me.
If I'm logged in from one browser (IE), shouldn't I still be logged in from a different browser (FireFox)?
Oh, and I emailed [email protected] last night and didn't get a reply.
Thanks!

Lisa

 

Hi Rob! Thanks for the link!
Logged in just fine after I deleted the FireFox cookies (FireFox>tools>options>privacy>clear) . I had deleted cookies/temp files last night, but didn't know FireFox had 'other cookies' and until I followed the link.
Problem solved.
