Used UVtools for halot mage

I used UVtools for halot mage however when I converted to *.cxdlpv4 it would not load on the halot mage printer when I used the USB stick.

I am guessing whatever file format you used before converting it is not compatible with cxdlpv4 so the file just will not work if you convert it. You would have to have it as cxdlpv4 to begin with.
