I need help, please!

I have one iPad that needed to be wiped, but now it can't be configured as I get stuck at the above message.

I have renewed my DEP token. My Apple Push Notification Certificate does not match the Push Topic mentioned on the help screen, ie “com.apple.mgmt.XServer.01ab0995-0663-4e2d-a001-25e9ef3eaf9e”, as we were migrated from ZuluDesk.

Could this be the problem, or is it something else? If this is the problem, how can I proceed without messing up my entire deployment? I don't seem to have the option to create a new certificate, and I gather that if I delete the existing certificate, everything stops working?

(Please answer in simple English as I'm tech support in my school more by accident than by design (I'm sure at least a few of you know what I mean). Thanks in advance!)
