File backup errorcode=2

I am trying to do a full file backup with incrementals. The client is running windows 7 ur backup version 1.5 and the server is running on server 2012r2 using urbackup version 1.5. When the file backup starts i get the following from the log file

Starting full file backup…
Indexing of “Users” done. 4126 filesystem lookups 0 db lookups and 0 db updates
ANRK-FARMOPS-15: Loading file list…
Error opening .urbackup_tokens.properties
ANRK-FARMOPS-15: Started loading files…
Creating directory “\Users” failed. (errorcode=2)
Waiting for file transfers…
Writing new file list…

Transferred 4.02593 MB - Average speed: 3.37214 MBit/s
Time taken for backing up client ANRK-FARMOPS-15: 4m 2s
Backup failed

The folder is created in the server under \anrk-farmops-15\yymmdd-hhmm\users but no files are copied

Any ideas
