I hit level 100 unlocking the various specilizations then boom, can’t unlock any more. I tried to maybe put in the code that was given to me through the Xbox live mail, but as expected, it said that it has already been entered. I’ve unlocked 5 specilizations so far but want to go through my last 3, even though stopping at an even 100 was fairly convenient…
redownload specialization priority alpha from your download history
thats a new one…
Don’t you just hate it when a guy prematurely… Level caps! See what I did there. ^.^
No but seriously thats odd, have you tried asking it politely? 
Try it when you’re disconnected.
