I don't need any support,
I am experienced user, but I don't have time to debug this problem now (I already downgraded to 2.0.13),
when I'll have it (time), I'll try to install this patch manually, from vim in console

, I'll write changes to every single line,
and then test login after each editing, when I'll find what is a problem, I'll try to do not forget to create a thread with a solution,
somewhere here on simplemachines.org...
