hello, i have the same problem bought killer instinct definitive edition on 03/04/17 and my purchase didnt apply to the base game either contacted customer, uninstalled and reinstalled the game 3 times, posted on the forums afterward and still issue not resolved. Called billing yesturday and had my money refunded and I finally get a response today to do the following for the windows store.
Thanks for the immediate reply. You may reset the Windows Store Cache. Kindly perform the following steps:
Press the Windows + R keys to open the Run dialog box.
Type WSReset.exe and click Ok.
The Store and a command prompt will now open with any message. The command prompt will automatically close after the Store's cache has been reset.
After its completion, restart your computer to sync all changes made. Then, uninstall and reinstall your game and check if the same instance occurs.
Keep us in the loop with the results after performing the solutions provided.
I was just wondering if this solution works since they removed all the content from my library in the store after the refund. If someone tries this solution let me know what happens maybe ill rebuy the content if they correct this issue. Ive been calling customer support all week to find a solution to this problem.
