Bad verison, server rejected error on Arma2CO server

I recently rented a 10 slot server from defconservers.com and when I go into multiplayer to connect to my server I get the error "Bad version, server rejected."

I have read online and seen how it is related to something not being updated properly. I updated ArmA2 to 1.09 just the other day, and I have Operation Arrowhead on steam so it is already updated to 1.59.

In the server info it says it is currently running on 1.57 which I assume is the problem.

I have no idea how or if I even can update my dedicated server to 1.59 but hopefully I'm wrong.

Contact the defconservers.com staff to update the server to 1.59.

Would I not be able to do it myself? Or do they absolutely have to do it?

It was such a simple solution..

You can do it yourself, I had a defcon server for almost a year, but if I remember correctly theres a tab there where it says server updates.

Look through control panel its there.
