I'm not sure why your upload did not go through at CB+. Narfstar today uploaded a scan of the 132 page ACG comic Hi-Jinx which, at 90.41 MB, was actually a little larger than your file for All Good Comics (89.78 MB).
Could you give it another try?
I had been trying to use their web upload page, and that had reported an error saying I exceeded the maximum filesize. I'll give it another try, and if that doesn't work I'll look into using their FTP option. (I think I used that once before, back in the days when the GAC upload page was broken.)
