Files Missing from Desktop but in Finder folder
I have to use Examplify as an exam system for school and I was trying to take an exam earlier today and the program froze while it was trying to close down all the programs on my computer so I had to force shut down the computer in the process. When I turned my computer back on my desktop was empty except for my background picture. If I use the finder I can find the items that were on my desktop but I can't drag anything onto my desktop, or right click on the desktop anymore. I'm not really sure what to do. Anything that needs to open on my desktop (such as the printer program for my school) no longer loads because nothing shows up on my desktop.
Any advice?
