ok, i feel a bit of a fool now...

thanks for all the lovely comments - and yes i am new to ps3!
after going over everything that's happened it would appear that my hacking problems were caused by a) an old wireless router with a **** (non-existent firewall) and b) an older version of firefox - have now updated to 3.5.
so i hold my hands up and will say i was mistaken - i was just feeling indignant at the time... bloody hackers!
you'll all be pleased to know that i have come up with a new system of remembering passwords and have dispensed with my word file...
(my god, i feel like at my first day at school..)
