Premiere Elements Immediately Crashes After Failing to Locate Files

Adobe Premiere had been working fine for me for a good number of years. Today I got a warning that my system had been running low on memory, after deleting some files I tried reloading Premiere and it refused to start. I tried every solution including deleting the cache files (1 TB worth!) and eventually I managed to get to the stage where Premiere was working. HOWEVER, when I tried to open up one of my pre-existing files it asks me to locate a file that no longer exists. When I click skip or mark as offline the system immediately crashes.
