Problem with CVS checkout

[Sairam]

hi,

    I'm experiencing a problem with the checking out files from a specific 
directory in the CVS server. The following is the error message which i'm 
getting on the WinCVS client i'm using.
      
    cvs [server aborted]: premature end of change in 
/cvsroot/repos/MultiVoIP/bin/mvpt1.bin,v

    Please help me out how i can rectify this problem and check out the files. 
This is very urgent.

regards,

Sairam S
