[PEDA] GND Net gone

[Elby Designs]

I have been using Altium Designer DXP 2004 with SP4 on Windows 2000 but recently had to change to a new computer now runnings Windows XP.
I have a project that appeared to be okay on the older setup but I have a problem with the current installation.

When updating the PCB file, having just compiled the project in the schematic section, the update refuses to recognise my GND nets. All the other power nets are listed but not GND. Is there anyway of seeing/editing/fixing the nets that the schematic section is working with that might explain why they are not showing up in the pcb?

Another minor problem is that any pads marked as NC or 0 (unsued pads on an SOT23 or ic for example) always come across to be joined together. Is there anyway of telling the system to simply ignore nets of this nature?

Best Regards
