I downloaded the Beta II, and I am upgrading from Beta I. Gets about 20% and fails.

Please see the testing guidelines …
For each new alpha or beta build start with fresh data: Using a fresh copy of your 5.3 data is beneficial to the alpha and beta testing program because it represents a normal upgrade from 5.3 and will help us detect any migration problems that might not occur when upgrading test builds. Also, bugs in previous alpha and beta builds can affect the current state of your data.

Ah yes well… I never had any 5.3 data. I did a fresh install with 6.0 b1, So I’ll go for broke and do a fresh install of 6.0 b2 
Thanks for helping test the beta!
