PGP on Vista (x32/x64) ???

I have been hanging out in Wilders forums for awhile, and I trust you guys/gals opinions. So I have a question for you that hopefully you can help me with:

I have been using PGP, but their lack of support for Vista (and XP x64) has led me to look for alternatives.
I would like your input on any security software that encrypts using containers or would encrypt the whole drive that works with Windows Vista x32 AND x64 versions.
I have tried (and been using on XP x64) Truecrypt, which is freeware, and works good, but they have not updated it to work with Vista yet.

I upgraded to Vista a few days ago (I have both x32 and x64 versions) and nothing works with it that I can find.

NOTE: I would like to get away from PGP. They have had a great deal of time to work on Vista and the (XP x64) verisons, and still nothing from them. Their support is terrible.

Thanks for your help.
