Updating working copy to latest format

I have not used SVN in over a year and when I try to update my working copy
I get a message

Working copy 'C:\Cio2' locked.

'C:\Cio2' is already locked.

So I tried to unlock and get the message

Working copy C:\.....\.settings is too old (format 10 created by Subversion
1.6 )

Is there a way to convert my old format to the newest format so that I can
do an update.

I have downloaded the 1.7.10 version and the about box shows

TortoiseSVN 1.7.10, Build 23359 - 64 Bit , 2012/10/08 11:46:26

Subversion 1.7.7,

apr 1.4.6

apr-utils 1.3.12

neon 0.29.6

OpenSSL 1.0.1c 10 May 2012

zlib 1.2.7
