Solved (was: Lost Racing Car Pack DLC from Academy Edition)

[tankuroded]

I woke up today and found out that my TCs and the X2011 had exclamation marks in their thumbnails. When I open the offending cars, I got the following message saying "The Racing Car Pack downloadable content is not installed. Please reinstall it."

The problem is that I have Academy Edition. I checked transaction details, there is no Racing Car Pack. In the GT5 DLC installer menu, it says Installation complete. What I must do?

EDIT: Done, installed the family upgrade and voila, the exclamation sign is gone. Please close this, mods.
