Adobe just released a new ColdFusion MX 7 Updater that works with Flex 2 (beta 3). This updater also fixes the EOLAS problem. We've received a lot of questions about this issue and the answer is: don't worry, Adobe will care of it.
Also, I highly recommend that you start playing with the new Flex2 (beta 3). It rocks :)
