iTunes March error 4010

I recently reorganised my iTunes library on my iMac. I grouped a lot of single tracks into albums to make my collection easier to manage. This synced very well on iTunes Match, and now I can organise my iPhone's iTunes easily. However, when I try to sync my MacBook, there are issues. Before reorganising things on my iMac, my MacBook was synced, but after I reorganised my iMac and synced it to iTunes Match, my MacBook has stopped being able to sync via iTunes Match. I keep getting the error:

"We could not complete your iTunes store request. An unknown error occurred (4010). There was an error in the iTunes Store. Please try again later."

I've tried now intermittently for about three weeks, and still my MacBook will not sync. Oddly, some changes had taken effect. For example many of my songs on the MacBook have been rearranged accordingly by genre as specified by the reorganised iMac. The main thing that has not synced are the new albums that I have given the 'loose' songs.

What do I have to do to get my MacBook synced completely? I don't want to have to manually reorganise my MacBook, every time I reorganise my iMac.
