The peeps above are right.......You can contact Recon Gamer support and they will enter the startup line you want or change server companies and go with:
https://www.osg.cc/index.php?module=...id= 3&meid=-1
They give you a web admin interface with room for two different start up lines which is very nice.... Their servers run very good too and they are very reasonable.
I have used ILAN, Recon, Crucial, WGO, OSG, and Clanservers, plus some I can't remember. The best, in terms of allowing you to change Tickrates, Maxclient Rates, web interfaces, performance are: OSG, wgo hosting, and Clanservers.
