looks like that string is used for icq/aim signed on passwords too :D
also , i just downloaded Astra, I saved 2 IM accounts but I dont see where their passwords are saved to , the old version used to have aim.ini,yahoo.ini,msn.ini but i dont see those files in the new version, all I see is the Astra user/pass in accounts.ini in the global folder which can be base64 decoded to the old xor scheme. so im guessing it doesnt save the IM passwords locally anymore?
