Im sure I have been a member for well over 2 or 3 years. I went into the account section. I was trying to get a diablo beta key and It says I dont have the achievement. How do I check this?

Any one know how to fix them.

you also need to have posted in the last year for that achievement (posting in the last several days might not do the trick as the process that calculates those achievements does not run all the time)
