aMsn doesn't use CVS anymore... We now use Subversion...
There will be some time where the package amsn_cvs.tar.gz will be out of sync so please be patient...
If you want to grab your own fresh copy from SVN, you can use the command
svn co
https://svn.sourceforge.net/svnroot/amsn/trunk/amsn amsn
or use TortoiseSVN if you are under Windows...
If you can't grab the fresh version by yourself, wait for the amsn_cvs.tar.gz to be resynced...
