Hi Michael, Resolving issues between the schematic and the board design can be daunting sometimes. What I try to do is eliminate as many variables as I can in troubleshooting and then add them back one at a time to find the offending issue.
I have seen the node not found error before and typically it is associated with a pin that is in the schematic that is not on the footprint. A simple mistyped name can be the culprit or a hidden pin... Check to make sure the name of the pin on the footprint matches the one in the schematic part. Does your schematic pass ERC? Look for duplicated reference designators, and netnames... things like that also... Let me know if that solves it... otherwise I may be able to help later with reviewing the files for you... but try those things first and see if you don't find the problem that way.

But now it's stuck on a node not found error and I can't seem to get it fixed. The error message says it's attempting to add node U222-28 to net RH, and the error is node not found. I've played with it quite a bit. At first I was getting many of the pins as nodes not found. I fooled with reconnecting the pins, refreshing the view, saving everything in save all, and even closing Protel and reopening it. I finally deleted the offending chip and placed another one. Now there's still one pin that it refuses to acknowledge. I also played with swapping nets hooked up to the pin to see if the problem followed the net. It doesn't. It stays right with the -28 pin. I've also tried deleting that pin in the schematic library and then adding it again. Any ideas would be appreciated.
