BB Torch :: Cannot Access Email Settings After Upgrading

I have a Torch running on the Italian provider TIM. I recently upgraded the firmware to version 6.0.0.2534 and since then I am no longer able to access my email account settings or add a new email account. I downgraded to the previous version, but still the problem, upgraded again but no luck. Every time I try to access my e mail settings it tells me to contact my provider, and sometimes the phone just freezes. I've tried all the various battery pulls but nothing. After spending hours on the phone with my provider, they tell me that the problem is not theirs but Blackberry!
