Here's what happened. I was entering some new comics into comicbase. I don't know which version but it was working fine before yesterday. then when I tried to enter a mag, the drop down list would not show me the CGC grades that I had manually entered years ago. cgc grades for my comics that I put in before WERE showing. I just couldn't enter new comics.
after closing comicbase, then rebooting, etc, the problem wasn't solved. so I upgraded to the latest version on the registrations page. that's when the problem got worse, as the cgc grades for my comics disappeared.
so I just tried to go back to an earlier version of comicbase -- now v188.8.131.5208 -- and the problem exists. this picture shows the problem. my comics that are not cgc, like # -1, shows the grade. but my comics that are cgc, like 1, 2, 3, 4, 5, 6, the cgc grade has disappeared.
