E-mail setup HELP

I am having so many problems with setting up my e-mail on my blackberry Torch.
First of all, I cannot even click on the E-mail button under my Setup menu.
Secondly, I tried logging into my existing account on the BIS website via my phone, and a popup message keeps telling me that I cannot log in on a desktop, even though I am not. I have previously been able to install 2 email accounts on my phone, but then deleted them because I thought I didn't need them, but now I do. Any advice would help! Thanks
