All That Remains Rock Band DLC now available

Riddle:
In the eye of God, No man will stand.
In the eye of Mother Nature, No building will stand
In the eye of ......... , One Man will stand.
Who is this man and what will he stand for?

Has anyone experienced issues with DLC since updating Rock Band and exporting tracks? Last night, two of us tried playing some DLC and we noticed 2 things:
1. When selecting songs, the on-disc songs would play samples in the selection screen, but none of the DLC would play any sound.
2. After selecting a DLC song to play, at the LOADING screen, we'd get an error message along the lines of "your session has been restarted, press continue and try again".

I tried a few hours later, just by myself and the DLC worked. So, is something wrong after the update/export?

I'm curious if the new DLC will be just for Rock Band 2 or for both. I'm getting RB2 anyway, so it's a moot point.

I noticed during the license transfer that Still Alive is listed in the Marketplace under RB2 now.
