Alchemy library big bug

Guys, i need your help. When i upgrade to the Logic Pro X 10.2, i like all of you, got Alchemy instrument. It has been downloaded and installed. When i opened Alchemy at first time it shows that it is refreshing his library. Ok. But after one hour it still remained "refreshing library". The presets window was empty, so i couldn't use anything from Alchemy. I came out from Logic, reboot my mac, open Logic again and open Alchemy once more. No changes. It still shows me that he refreshening his library. OK! I decided delete Logic with all his stuff and download it from scratch. I imagine my surprise when I opened Alchemy and saw the same thing! It has passed a lot of time but i still don't understand what is wrong and why it still doesn't work! Can you help me guys?
