LR Classic will not start when I click to open- HELP!!!!

[VMCasas1121]

I am compleelty freaking out today! Last night I went to open my LR Classic as I normally do, which I had done, right before a shoot in the afternoon...and it brought up this message:  Lightroom.exe -System Error The code execution cannot prceed because amtib.dll was ot found. Reinstalling the program may fix this problem. 

Does this mean I have lost all my photos/work/edits/catalogs? I am freaking out! Please help or share if this has happened to anyone. Also, I did an update the night before last, and it was working just fine then, it did what it did last night. I back up once in awhile, I did it the day before. 

Thanks in advance for any help!

Use the Creative Cloud app to uninstall LR Classic and then reintstall it. You will not lose your photos/edits/ etc.
