Awww man, Sorry to hear that the trial version expired.
Well if you do manage to get a copy and things are up and running you should check out this link for tonnes of flash animation tutorials. <a href="http://bbs.coldhardflash.com/viewtopic.php?f=2&t=459">http://bbs.coldhardflash.com/viewtopi c.php?f=2&t=459</a>
All the best with you game.
Hey and a small bit of advice, if you are not going to get heavy in to flash as3 and programming in general, look out for a previous version of Flash ( CS3 and lower) you might get it for a much lower price.
