Hello, 
i have problem with my serial in MP.  
I have only one account on dcs. 
I've tried unbind serials in this page http://www.digitalcombatsimulator.com/myserials.php - nothnig changed. 
Then I tried this - http://simhq.com/forum/ubbthreads.php/topics/3606485.html - nothnig changed. 
, then i completely uninstall world and my modules. 
After new install it'works, untill i have installed DCS A10. 
On thins page http://www.digitalcombatsimulator.com/myserials.php I can see only Ka50 and P51 modules, but A10 doesnt appear on this page.   
Any idea ??? 
Thanks
