Moving from sure cuts a lot 3 to 4

[Moving from sure cuts a lot 3 to 4]

I recently upgraded from cuts a lot pro 3 to 4 and I am wanting to know if I can move the work saved during 3 to work in 4?

Will that stop it from cutting back over itself too?

Hello I am new here so work with me if I am not 100% sure what I'm talking about.

I am using Sure Cuts A Lot Pro and I can get the image onto the screen correctly but when I go to cut it everything cuts correctly except that the 2 and the 6 end up on top of the 1 and the 1. I have tried everything to get it to not happen this way but nothing seems to work. I have attached the image so what I am saying makes a little more sense.

Also i was sent items as eps or ai (not sure what that means) and when I try to open them in the program Sure Cuts a lot Pro they are not compatible with it or just wont open in it, the only thing I can do is print them and then scan them back to the computer, what do I do?
