Solved Software Issue?

Hello,
New to 3D printing, and am having a somewhat rough start. My current issue is the MatterControl software is not allowing me to print now. What happens is that when selecting print on an item in the library, it shows "preparing to print" as the Status but only shows "..." where you expect to see it showing you the layers, etc. And then the status just goes back to "connected" like nothing happened.

This started after I was screwing around trying to download Repetier-host, and I guess installed Repetier Server and it basically disabled my USB port that I was running on the MatterControl. Finally got it resolved, went back to MatterControl, had issues with super slow printing, reinstalled MatterControl and now get this. Ughhh.

Any ideas would be appreciated. Really enjoy this when it works. (Most of my rough start happened straight out of the box, y-axis belt holder broken, cables wrapped wrong way around z-axis rod and under heat bed. ughh).

 

Thanks Mark! Had some trouble connecting to Repetier, but worked at it and its now connected. Do I use exactly the same figures/settings in Repetier that is used in MatterControl? Thanks!
