Help Needed- File lost and submission is in 6 hours

Hi all :), i had been working on a file in TwinMotion for the last few days and i finally finished it with no immediete errors. But just like that i can now no longer access it.
Basically, i had completed my model but noticed that it has started running quite slowly, so i restarted the software as i wanted to take my final video walk through and after this i started getting crash reports as the file wouldnt open, so i thought this may be ralted to the fact that a new update is avaiable and has been targetted at ficing bugs, so i did just this. Howveer, once it installed i then tried to locate the file taht i was working on and it was no longer in the recent projects tab, so i then tried to locate the phsycal file (which i had done many times prior) and now it is not there, all that is left is texture files, crash logs and no file. This file had been regularly saved but there is now no twinmotion file. It has also done the same for all 5 models that were once in the “recent projects” tab.
Does anyone know how to correct this, it may be a silly oversight, however, id really appreciate a solution as i havea dealine fast approaching and i was aiming to have this video complete by now.
Thank you very much.

Wow… feel for you…the only thing I could sugegst is downloading a file called “everything” its a search tool. Then search for *.tm and see if any of the autobackups appear. Copy them to a folder to your desktop and then open TM and try loading tyhem… Good luck,
