1. Run winetricks flash

Instead of installing flash it redownload package because a checksum error. Adobe has just released a new version of flash.

I've done a patch with new checksum.

Btw I use winetricks-alpha but checksum should be the same for normal version

to install patch you have to use patch command

There was a bit more to it, see http://code.google.com/p/winetricks/source/detail?spec=svn107&r=107 Fixed, thanks. (I guess I have to start running winetricks-alpha-test on a clean cache.)
