FIRMWARE PROBLEM DSO 203 hardware v2.6

I bought 2 days ago a dso 203 withHardware v2.6, firmware ypgrade v3.10, SYS v1.31, APP v2.31.
And by mistake I try to update the firmware to v118.
Then I saw that the new pcb doesn’t support for the old firmwares…
So now asks for something…Enhased Licenced number …XXXXXXXX
and count down a countern every time I switch on.
Can someone help me with the new firmware…where can I found it again?
