I did have some problems with my X55 but reinstalling it from the scratch made it usable again. Although I'm still having some issues when using Athlonics profile for A-10c. If I unplug my controller with Athlonics profile enabled I always end up on blue screen. So I just need to load new profile every time I quit playing. Sometimes I don't remember that and already broke my motherboard with those blue screens... Anyone else having the same problem with that profile?
(IGP and XMP-memory profiles are gone, tried reinstalling BIOS and tested my CPU + RAM on another computer, both were fully working.)
Other than that the stick + throttle works flawlessly, I'm using it trough my keyboards USB-hub.
