I also got into LOL beta a week or so ago, but I've been busy so I haven't had time to tinker. If you haven't already you should check out the following 2 links: Looks like other people have gotten Adobe AIR to run fine: http://appdb.winehq.org/objectManager.php?sClass=version&iId=14843 Perhaps we need to try downloading and installing Adobe AIR independently first instead of letting the LOL installer do it for us. And then check out Winetricks http://wiki.winehq.org/winetricks There are a ton of little tweeks to solve a huge range of problems that you might have. Anyway, this might not help, but I'll be tinkering with it soon and let you know where I get.
