For anyone else who runs into this problem. Check out your registry hive. To do this hit control , alt , delete and go into the task manager. From there click on the processe tab and turn off spool.exe, anti-virus, firewalls and anything else that isn't required. You do this by right clicking on a service and a popup willl appear asking you what you want to do.
MAKE SURE you only do this on systems that are only being used to run Mach3.
Each of these services take up a portion of the memory that you have installed. By not allowing these services to run your free up memory for Mach3 to run.
