Update from official v1.0.2 (fresh install) to the 2004-03-11 nightly, and got this :
[Error on rename of '.\account\#sql-d80_3d.MYI' to '.\account\wp_users.MYI' (Errcode: 13)]
user_activation_key VARCHAR( 60 ) NOT NULL ;
Just wanted to let people know... Not sure if it's gonna ruin my install... If yes, I'll just reinstall the whole thing.
