Another alternative is you can click to allow on account amounts and book this way. But then it doesnt have the same tracking options as you do with a prepayment number. Might this work for your customer?
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
