Getting Started Errors?

[Dagotte]

So I just got a Mars Pro 2 and followed the setup instruction to the letter, but I am unable to print the Rook test file. I keep receiving "The resolution of the sliced file does not match the screen!  -1440"". I followed some some suggestions found on this forum without success. The ChiTu Box software is prompting me to update versions, but won't update.

I tried matching the printer resolution in the software and reslicing the file, but no luck

Any Suggestions or help would be appreciated!
