Unable to buy left 4 dead 2

I have tried many times to buy l4d2 but I keep getting the same message “sorry cannot comple purchase”. Any advice?

:)

 

Previously owned game and DLC not appearing on my account

The links to the Left 4 Dead 1 DLC you just posted said "Already Purchased". The links for the Left 4 Dead 2 DLC asked me to buy them again. We've gone full circle back to the problem of I used to own the Left 4 Dead 2 DLC but it's asking me to buy them
again.

But I do appreciate you clarifying the DLC's contents.

 

left 4 dead the sacrifice

you have to buy both version of the sacrifice to play it on both games. you brought the left 4 dead 2 version of the DLC so you can only play it with left 4 dead 2
