Don't mean to repeat the post here, but haven't had any luck anywhere else:

I've installed 4.5, and a trial version of docs to go Premium edition. Since that time, I can't open attachments, or even open the menu in emails with attachments, that have been sent via BES. HOWEVER, the same email/attachment works normally if I forward it to my BB via my personal email. I've deleted BBeamer thinking this could be the problem. It's not. I removed docs to go premium, and the problem still exists. So I'm assuming it must be something with 4.5 and BES. Anyone?
