You must add this line in group admin in acl.xml to work!

..\MTA San Andreas 1.4\server\mods\deathmatch\acl.xml

---------------------------------------
<object name="resource.login"></object>
---------------------------------------

To be like this:

---------------------------------------
<group name="Admin">
<acl name="Moderator"></acl>
<acl name="SuperModerator"></acl>
<acl name="Admin"></acl>
<acl name="RPC"></acl>
<object name="resource.admin"></object>
<object name="resource.webadmin"></object>
<object name="user.YaSser"></object>
<object name="resource.login"></object>
</group>
---------------------------------------

Then change file name from:
"login-YaSser.zip" To "login.zip"

Have Fun !...
