Why do prints on Repetier Host not start, when manual heating and motor controls work?

I am running a RAMPS board Prusa i3 on the newest version of Repetier Host, and everything worked fine on the last computer I had. I set Repetier up on a new computer, and everything functions as it should except that when I try to start a print, it says a print is in progress, but it's not printing. The stop/pause buttons are there as if a print is in progress, the bottom right corner forever says its printing layer 0, and the manual control window does not show a print in progress. Testing has indicated that the motors and heaters respond correctly when using manual controls, so the problem isn't the connection, baud rate, etc. Nothing was changed in terms of the hardware or firmware of the printer itself. The print runs fine using the virtual printer simulation. I also tried deselecting the box for "check extruder and bed temperature". Does anyone know what would cause the print to fail to start?

0.3mm nozzle printing speeds?

I am currently finetuning my homemade hotend and was wondering what you guys have in the speed settings for 0.3mm nozzles printing ABS? I started with the aim of reaching 120mm/s but after some hours of finetuning I am currently trying to breach the 200mm/s barrier. As I am only using a very old Mendel Prusa I am actually quite happy that I got that far. What speeds are possible with the current printer models? (not the statements on the website, real life)
