RedMC Problem: "x16"

I've been experiencing an issue with RedMC. It gives me an error. It displays this error --> "x16" and it opens up many file explorer tabs and then the software just shuts down. Anyone know how I can fix this issue?

I haven't run into the x16 thing, but RedMC has definitely opened a shit ton of folders for me, as well. Restarting the program usually fixes it for me, though.

Restarted the program and still not good.
