Someone mind explaining how this is possible?

Okay, so last night i was on the server, the arena server was fine and i was able to connect and everything. I'd just finished the installer for the client and it was getting late so i closed the server down (after being on with some friends and playing perfectly fine). This morning, i come down, turn the computer on and decide i'll start working on the scripting and BOOM, suddenly i can't access the Arena server and after a while the NPC server crashes. i went to fucking bed, how the hell can it corrupt like that without me doing anything D:

I checked the field server as it said "Field server has stopped working" and i'm faced with this error that doesn't appear to be in the forum as the search returned no results:

[ERROR] WRK DQP_ReloadWRKServiceList# self setting is invalid !! ServiceUID(0) ServiceName() ServerGroupName()

and other than that i can find no other errors, the ports are set up corrently so, in theory, the arena bin should be able to connect to the fieldserver bin.

I'm stuck as hell and would appreciate it if someone who knew what they were doing was able to shed some light or point me in the right direction.

Please can someone take some time out to see if they can help? i'm growing tired and would really like to not have to start again...

Dont expect much help from people here, but i can tell that WRK is world rankings. So something about them is broken.

PS: only reason why i replied is cause you actually use proper english :V

If you need help, then you must also post the necessary information we need to help you. FieldServer Logs.

Well, with the world rankings, there is an expected error is there not? due to the fact that we cannot connect to the correct servers with the detailed information on every player in the world.

Just so you know, it's the Arena Bin that is outright crashing and the NPC server slowly dies but in about 1/20 attempts the npc server boots correctly and mobs spawn.

The field server log is attached.

Just so you know Pan, i am from england so i'd be surprised if i didn't know how to speak it ;)
Nah, i'm just someone who is trying to figure all this stuff out, the coding is part of my Uni course so i thought i'd start learning by editions to the current files but i can't do much of that is the server decides to break itself you know? anyway, yeah, if there's anything incredibly obvious that's wrong in the log, slap me and tell me what to do :3

Thanks
