Problem with file name and opening a file

Okay, this is weird. Earlier today, I saved the file I was working on (attached), named, "New Funnel in MOI." I'm finally almost done with the Sims-class funnel that's been occupying my attention for awhile now. Okay, here's the weirdness. The file will open, but there's nothing on the MOI screen. After right clicking the file and inspecting it, the file name appears to be, "New Funnel in MOI.3dm.3dm." Like I said, weird - that's never happened before. There are two .3dms in there, and I'm surmising that is the issue. I've tried renaming the file to eliminate the extension, but still no go. Renaming it does not solve the problem.

Any help on this? I have the base file stored and backed up, so no worries there, but I'd just finished some small details and upgrades to the part that I'd like to not have to redo. I'd prefer to just open and work on the existing file.

Thank you!

Bob
