r/nspire

Hi all sorry if this is a bit silly but I got my first nspire yesterday (nspire CX II-T), and I've installed ndless for OS 6.4. I'm trying to install scummvm which is available on tiplanet, and I'm not able to cut the file to move it into its own folder. Anyone have any general advice? Is there a way to do it on a windows PC for the CX II-T? Thank you in advance

Any ideas why this may have happened?

For some reason when i try to put "solve((x\^3)/3-4x=10+2/3,x)" into my CAS calculator it gets stuck loading until i reset it manually. I can find the answer using a graph and intersection so I don't know why it reacts like that to using solve.
