Hi Phil,
I don't have a lot of experience with the advertising and marketing bits in
CS but I can confirm that you are seeing an overflow exception based on the
error code. I'm assuming the component was working at a point in time. Has
the only change affecting the advertising components since then been the
growth in page groups?
Cheers,
Colin
