I am unable to create ticket. I created an account. I get a message saying the account is created. I log in and click on create a ticket. I get a message that I have to create an account before I can log a ticket. I have XP SP3 and this happens in both IE 8 and Firefox 5.01
Whilst I have no idea why you are unable to create a ticket, it would probably be much quicker just to post the problem here in the forums.
I can understand your having IE8 as that is the highest you can get in XP, but firefox 5.01 is well out of date, now on firefox 11.0.
