[Alexey Gaynulin]

I've following massage of my problem:
"bzr: ERROR: Could not acquire lock "Z:/home/visa.new/www/.bzr/checkout/dirstate": (32, 'CreateFileW', '\xcf\xf0\xee\xf6\xe5\xf1\xf1 \xed\xe5 \xec\xee\xe6\xe5\xf2 \xef\xee\xeb\xf3\xf7\xe8\xf2\xfc \xe4\xee\xf1\xf2\xf3\xef \xea \xf4\xe0\xe9\xeb\xf3, \xf2\xe0\xea \xea\xe0\xea \xfd\xf2\xee\xf2 \xf4\xe0\xe9\xeb \xe7\xe0\xed\xff\xf2 \xe4\xf0\xf3\xe3\xe8\xec \xef\xf0\xee\xf6\xe5\xf1\xf1\xee\xec.')"

Since i've got it i couldn't commit, view history, and, saying in few words, work with my project.

Looking forward for you assistance.
Thanks in advance
