This beta updater cleans up after two oddball problems: a rare issue which could lead to the program looping when installing updates which involve a great many changes; and a fix to error messages which would occur if you sold an issue on Atomic Avenue, but deleted the issue's record in your ComicBase before deducting the sold item.
Have these problems happened to you? If so, try out the beta updater at the link above and let us know what you think at support@comicbase.com
