motochopper wont work now

I have WW_V10.6.2.8 and JB 4.2.1 stock. motochopper used to work just fine. But since the last OTA update it has stopped working and I get a Failure message at the rooting step (same as the screenshot above). Not sure how to root now. Any help will be appreciated.

Either downgrade where it worked or unlock the bootloader.

I do not want to unlock the bootloader.

The version that worked was 10.6.2.6 but how do I downgrade? It says on the Asus download page "Firmware update cannot do *SKU conversion* and downgrade version".

P.S. I do not want to lose my data / wipe the tablet.
