Mach 3 Will not connect to my milling machine

Hello
My old pc has sadly expired.
I tried to reload Mach3 into my replacement machine together with my profile from the old pc.
Mach 3 loads up ok and the settings for the profile seem to be correct.
However the display digits for the X,Y and Z axis are in a thin font unlike the 4th axis which is displayed in a thick bold font (as the XYZ display should be)
When I connect to my milling machine and try to operate the table the mach 3 XYZ display increase/decrease but my machine does not respond.
Has anyone come across this anomaly.?
Any assistance would be greatly appreciated.

Largish field.

What´s your controller hw ?
Smoothstepper ESS, Pokeys, CSLabs CSMIO, PP, something else ?
Does it have a plugin installed into mach3 correctly ?

Look at diags / plugins.
Your controller shuld be visible, if it is installed.

Are your using flash screens ?
It´s a tickbox on the settings (last) page.

First guess is that your plugin is not installed.
Take pics of your hw box and we can say what you have.
Take pics of your setup screens and we can guide you.

We really need more details.

However, the first thing that springs to mind, is if you're using the parallel port, is the new PC 32bit?
Mach parallel port driver will not work on anything newer than win 7, or anything that is 64bit.
