Yep Sixpack rocks with all the info and updates
I was still having problems reporting with the fix, maybe it was the server I dunno. I also know of at least one person who lost some work but that was also related to renaming the original client I think. In any case, for me renaming app_info.xml and then running the app worked fine, in some cases the default exe is downloaded, but renaming that too should run the optimized application. Whether different optimized clients will respond exactly the same way I can't say, but thought I'd share what I experienced in case it helps anyone with probs.
Cheers!
