prob. with 5.1

When I try to bring up my server with 5.1 it loads everything perfectly (I have run a 4.4 server b4). Then when I click on World.exe it gives me some errors like missing items and stuff like that. Then I click on boot5zones thinking everything is working fine then when it says loading such as [loading]:sharemem (or something like this) then it just freezes on me and its pretty much stuck at that point. I think its something wrong with the package I downloaded from you guys. I followed the normal stuff I usually do with 4.4, like make a new database and a new thing like /create database eq551, then use eq551, source db.sql. Then text flys by then I change my login and other files to read off of that database, change my mysql pass and login info. then click on boot5zones put my external IP in there and click world.exe shrink it down, and click boot5zones and 5 things pop up then freezes on me. I have no prob. in 4.4 but in 5.51 this prob. pops up.... wtf is up with this?!
