An unknown error occurred while opening the project

PLEASE HELP. I was in the middle of editing a project which I have been working on for a long long long time now and I realised I had accidentally duplicated a couple of files, so I began deleting them and as I deleted them, an error message came up and said that there had been a serious error and my project had to be closed.... all the files then went red and premiere crashed. (FYI i've also been using warp stabilizer if that helps and other manipulative effects)

Now when i go to reopen it, it begins loading and an error message comes up saying " an unknown error occured whilst opening the project".

This isnt the first time something has happened like this either.. the program keeps crashing, deleting files and being unresponsive constantly! Which is really unreliable and I'm actually distraught as to how delicate this software is! I have now being scrolling through tons of forums trying to find an answer which no one can give me. I've just payed a lump of money to use this program and actually feel that I should be reimbursed and compensated for the trouble I repeatedly am encountering.

I've also tried opening it through the media browser, but when i double click on the project, it opens up but contains no contents.

I am currently 4 days away from my project deadline for my final major project on my course and I do not have the time or patience to do this..

Someone PLEASE HELP!
