Same advice as before. Most likely something wrong with your computer.
How it got messed up is a mystery only you can investigate. It surely is
related to a change (recent or otherwise) which you did or was did to
you (malware).
No telling what software provided by the school. My understanding is
that some schools do give the Trial Version (which has a limited life
span on the computer) for courses since it's free. I have no knowledge
of what licenses are available to schools or your school; talk to you
school to find out what they gave you. I'm sure your instructor can
explain to you what license they gave you. If the trial version (which
you can also download from Microsoft) it has a limited life span.
The point of projects is to deliver the deliverable. Using Microsoft
Project is rarely a deliverable. This is now a learning experience for
your in project management. Your deliverable is a Gantt Chart to be
delivered the day after tomorrow. Before you started this project you
had a *risk* which hopefully you recognised but you chose to "accept":
"Because I am using a computer, the computer may some how or another
fail due to file corruption, malware, hardware failure, or other means
which could lead to me not having the right resource to achieve the
course deadlines". This risk has now come true and you have an *issue*:
"My computer does not work I do not know how to hit the course deadline".
I would recommend you stop worrying about your computer, focus on the
deliverable. See if you can use your friend's computer. It apparently
works.
Then, later, fix your computer--buy a non-trial license Project, or use
Windows System Restore to attempt repair, or (what often safes most time
and avoids having to figure it out), re-build Windows and applications
on the machine and restore data from backup. Something broke you computer.
