Hi fatma,
did you restart your IS after enabling VCS? This error occurs when you try to configure repository without restarting IS.
According to the documentation webMethods (Storing Services in a Version Control System):
To configure the WmVCS package to work with Subversion
1 In Integration Server Administrator, go to the Solutions > VCS > Edit Configuration page.
2 In the Select Version Control System list, click Subversion, and then click Save Changes.
3 Restart Integration Server.
Connecting to Subversion for the First Time
1 Go to the Solutions > VCS > Edit Configuration page and click the Advanced Settings link.
2 In the Subversion Repository Location field, type the URL for the Subversion repository.
3 Click Save Changes.
4 Restart Integration Server.
