Restart Lightspeed Application after Quitting

[Bece Kidder]

Hi,

I purchased a used Lightspeed about 6 months ago and I love it.  There is one issue that has been bothering me.  If I close the Lightspeed interface or application, I cannot reopen.  It says something to the extent that the application is already running.  At that point I have to restart my computer and go from there.

Has anyone had that problem and is there a way around it aside from restarting my computer every time?

Thanks,

Bece
