Score upload never stops the upload process.

One of my scores, about four minutes SATB and organ, never finishes the process. I have found there is only one score that does this, and despite reverting to older versions and updating edits on this version, it still keeps going on the website. Although the upload keeps going, terminating after 10 minutes, rather than one or two minutes, does create the latest version. I am worried things might get worse, but it only applies to the included file. Has anyone else seen this error and found a remedy for it.
