Problem install aTV Flash 4.0.3 to USB

EDIT: Never mind… restarted my Macbook Pro… ran Repair Permissions… tried again and it installed correctly.

I’m using a Sandisk 2GB USB Flash Key that I’ve used many times before to install aTV Flash but not having any luck with 4.0.3. I downloaded aTV Flash but when I try to install it it partitions the key with no problem but then gets stuck at Copying Files… 0%. Let it run for 30 minutes and it never progressed from that point. Tried downloading aTV Flash again, downloaded the OSBoot file again, tried to install to a different flash key… no luck… keeps getting stuck at Copying Files… 0%.

Any advice would be greatly appreciated.
