Prestashop 1.5 Multistore (mod_rewrite)

I have just installed the newly released prestashop version 1.5 and iam trying to use the multistore function. But it says Warning: URL rewriting (e.g. mod_rewrite for Apache) seems to be disabled. If your URL don't work, please check with your host provider how to activate URL rewriting. But i already have url rewriting enabled!! i tried to see my [login to view URL] and searched for mod_rewrite and could not find it, but maybe it shouldnt show that anyway? i have my own server with cPanel Server information: Linux #1 SMP Wed Mar 7 00:52:02 GMT 2012 x86_64 Server software version: Apache/2.2.22 (Unix) mod_ssl/2.2.22 OpenSSL/1.0.0-fips mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP version: 5.3.16 if you want to do any changes, you will get access via teamviewer only Please look at the attachments
