I am currently trying to host an Unturned server remotely after my local server, which ive hosted for almost a year, got DDOSed and our ISP threatened to end my internet service contract

First of all, what current core-configuration for VDS/VDP unmanaged system are you guys using? I am using a 2-core configuration but should I change this to a higher one or lower?
Second of all, after I installed Steam + Unturned on the VDS unmanaged machine and run the server batch file, it seems Unturned crashes immediately. I am thinking this might have to do with the Unity 5 engine that Unturned is using, as the Windows Server 2012 R2 did not come with any additional software (understandably)
Any assistance on this from those currently hosting Unturned with NFO?
If you guys can also tell me what configuration you are using (in terms of VDS/VDP and how you set up your serv in the virtual machine) that would be greatly appreciated
My server group is here if you want to Czech it out
