2nd Life not working on new intel iMac

Help, I've been happily playing SL on my old iMac and have just upgraded to a new 2.4 Duel Core Intel model. I unpacked it, transfered my SL applications to my new machine and now I find it won't open. I just get the crash report come up. I tried logging on to the SL website again and downloaded the mac application from scratch but I still can't open it.
Somebody please tell me they are playing on one of the new iMacs. The only reason I bought one was to play SL.
Anyone got any ideas? Please!!!!!!

No problems here. Don't know what to tell you. Upgrading to a new machine can sometimes introduce a few unforeseen surprises. Usually its something that's so obvious we overlook it.

I managed to sort it thanks.
I hadn't deleted ALL of the 2nd Life files before downloading the application again. This time I located all of the associated fles, did a 2nd download and it all worked fine.
Phew!
