http://ck.kolivas.org/apps/cgminer/temp/Since this may be a recurring theme, I've uploaded a new bleeding edge binary for both windows and linux into that directory which can work around the problem but will give a warning when it happens. I'll try and keep bleeding edge binaries in there if/when required.
Starting with --verbose with these binaries should give you a lot more information which will help you debug where devices are going as well if you're having a new ordering issue.
