Thanks, Sam. I received an email from a member of EAA staff with the new instructions. I asked him about the Electrical/PCB issue and was told that the Electrical Schematic module is automatically installed with the core program, and we just need the second serial number for the PCB module. I re-started the installation and can confirm that this is the case. The installer showed the modules that would be installed, and both Schematic and PCB were listed. My computer is working on the massive download now.

The new instructions pretty much mirror what we discovered in the thread above. Those new instructions should be posted to the EAA website, at Step 2, here, but if you're still getting the old ones, and you didn't get an email from EAA, send me a private message and I'll forward the EAA staffer's email to you directly.

I'm not going to post his email address publicly for obvious reasons, and I'm not going to send serial numbers via PM, so please don't ask. It's too easy for a non-member to register for the forum and send a PM.

Thanks to the fine folks at EAA HQ for helping to get this sorted out, and for publishing the updated instructions!
