unable to obtain lock and no branch in /bazaar/2.0/lock

hallo,

when trying to close the window from bzr qlog I receive the following message:

Unable to obtain lock file:///C:/Users/juri/AppData/Roaming/bazaar/2.0/lock held by Juri <email address hidden> on il-c-win54 (process #5496), acquired 210 hours, 17 minutes ago.
Will continue to try until 07:37:50, unless you press Ctrl-C.

I tryed with bzr break-lock but I get answer:
C:\Users\juri\Desktop\comm betwin wp and apdp>bzr break-lock file:///C:/Users/juri/AppData/Roaming/bazaar/2.0/lock
bzr: ERROR: no branch: »C:/Users/juri/AppData/Roaming/bazaar/2.0/lock/«.

This directory exist, but of course it is not branch.

Thanks.
