XYZ Da Vinci Pro EVO: Got it for free, already a headache

My after-school program recently acquired two XYZ Da Vinci Pro EVO 3D printers. These were given away to us after some simple training. My boss and I were very excited to have some seemingly user-friendly printers with built-in bed leveling. It took less than a week to become a pain.

First problem: Only one of the printers even works so far. Both turn on, but one immediately says there is a firmware issue and needs help from support (turning it off/on does not resolve it). Support responded over the weekend to point me to the XYZ website where the links for firmware updates no longer work. Waiting to see if the respond to that.

Second: XYZ Print 3 suddenly stopped working over the weekend. This printer only works with .3cp files, which only come from this particular slicer (as far as I can find). I printed several small projects last friday with no issue. Today, for no apparent reason, every time I try to save my sliced files I get a "-22 Error". Then the slicer crashes. So no saving files to print on USB for convenience.

Third: Even with problem-the-second, I can just move my laptop to the printer and plug it in for a print. Less convenient due to my room setup, but whatever. The brand new problem is that the printer ignores the actual project I have loaded onto XYZ Print 3 and just prints the previous project all over again, which baffles me since it was done from a USB that is no longer plugged in. Restarting the printer and laptop has not solved the problem at all.

After looking around and hearing so many awful reports about XYZ products, I won't be surprised if there isn't any hope for these. I was really excited to expand our STEM program to include 3D modeling for our youths, like with TinkerCAD. If anyone knows any way to help, I greatly appreciate it.
