You are at right place for the solution, if you faced the error message like above while using svn client.

Reasons why this error occurs:

1. You have installed a newer version of svn client on your machine, and trying to add/commit some new files to svn server from you current working copy.

 Easy fix 1:

1. Go to your svn checked project > right click > select 'upgrade the Working copy'
1. This will upgrade the working copy and now you should be able to add/commit file easily.
   

Easy Fix 2:

1. Still after applying the fix above, issue is not fixed :(. You can try below then:
1. Right click on the folder causing the issue.
2. If on right click it does not have any svn 'upgrade the working copy'
3. Then go under the folder delete the ".svn" folder completely
4. Add/commit the remaining files to svn :) it will no give any error :)
