How to fix this error 'cvs [checkout aborted]: no such tag r20120711' on php eclipse helios?
===

I am using php eclipse helios for debugging php code and using CVS as repositiry.

Under CVS repository there are 3 -

    head
    branch
    version
and head conatins the repository of server.

Under head again I have 3 

    bms
    cvsroot
    news4u
To create a new branch I used to click on news4u and select a option 'add to branch list'.
But accidently I selected 'Tag as version' with name r20120711 and after that I have created a branch by same name.

Now if check out is taken, it gets check out partially and gets failed and if tried to commit the resource, it says, `'no tag is found by that name'`.

How to fix this.
