Incopy Story bar says "In use by (Me) & (Indesign File that doesn't exist)" and unable to check-in

Not certain if you've ever found a fix for this, but I wanted you to know you aren't alone. I've had the same thing happen where I use an Incopy file containing our copyright info, placed in a very large number of InDesign files. I have separate Incopy files for each language that we translate it to. However it is our Japanese file that is the one listed as the file that is using our English copyright Incopy file. This is not true, nor does it exist within that file anywhere.
Here is where things get weird... I actually created a brand new InCopy file and retyped the entire Copyright info from scratch. Then I saved two versions of that file, one with the suffix '-new' attached and one with the original file name. Now this file is brand new and not connected whatsoever to the Japanese file that seems to be causing the grief. However, now when I open the brand new English Support file in InCopy it still maintains it's in use by the Japanese version even though I haven't opened the Japanese version, or the Japanese copyright file at all during this resaving process. By comparison, the one i saved with the '-new' suffix works just fine, no odd links to alternate files or universes whatsoever. 
If i've explained this clearly enough, the strangeness of this should be clear.

There's no where near enough info here. Has that file been placed into an INDD file? Did you close it without checking it back in? What version of InCopy? Are you working alone or with someone.

Please provide full details on this.
