File IO error - can anyone tell me what this means?

One till is freezing occasionally - doesn’t seem to be related to a particular activity. When it freezes (maybe once a week during normal usage), I am getting no error report under the Sambapos logs (so it doesn’t look like a database issue). This is the message I get under the windows system event logs (below). Does anyone have any ideas what the problem might be? Thanks!

That is probably key. What file that might be I have no idea. Sounds like a system issue and not SambaPOS related but its hard to tell.

If you ask me it sounds like a .net issue. I would try repairing the .net installation or reinstalling .net

Ok that makes sense. I’ll give it a try, thanks!
