not working/ free simulator

[qwert12]

free simulator wont load.it starts and charts come up but wont go further. cpu at 100% task manager says process wont load.waited 10 minutes wont work. tried many times . unistalled software and reinstalled still didnt work and still had previous charts coming up not loading. installed latest version.
ninja trader will not work at all if i open mozilla firefox first. u click on the icon fr ninja trader and the loading circle comes up for second and nothing happens. using vista.
i adjust the techincal indictors alot , is this plugging up the program? 6 charts open , 50,000k of memory usage for ninja trader in task manager. charts cant be closed.

Try with only one chart open with zero indicators. You will need to first setup the start price for the simulated feed through the Instrument Manager to see any movement.
