[Plugin: Plugin Name: accelerate your advertising] Not compatible with wp2.8 someone please HELP

Hello,

This seems to be a useful plugin but it does not work with wp2.8 and the authors blog has not been updated for half year.
It seems to be very simple, less than 100 lines of code, but I am not good at php so could someone please have a look what needs to be edited to make it wp2.8 compatible.

Thanks
