Cannot apply upgrade?

Francois G. 1031

I tried to apply the 250MB upgrade but I think it doesn't work.

 

I see the top box wiggle but then it stops and the upgrade is still in the pop-up box below.

 

I'm I missing something?

I had the same error, give your account a day or so to settle, disable all adblockers/popup blockers and try again. You need to have 1 slot 'unlocked'. I just kept trying every now and then and it eventually locked in and worked, hopefully they'll solve this issue.
Other people had the same issue, and solved it by spam clicking it until it worked apparently.
