Lost v54 of my backup and can't restore

When trying to recover my computer acronis is telling me the v54 of my back up is lost, every other file of the back up it there (v1 through v53 and nothing beyond v53). I thinking since my computer states the folder the backup files are in hasn't been modified since the backup that there wasn't ever a v54. Anyone know any solutions? It doesn't give me the option to ignore v54 even though the dialog states I should be able to, the button to ignore v54 is just not there, but the ignore button pops up if it ask for other versions of the backup (even though for those i click browse to show it where they are)
