Okay, the folks at Chief Architect suggested doing this. Kudos to them... they gave me solution that didn't require a full software upgrade. I'm very impressed.
I was a Chief Architect user for 10+ years. I'm semi-retired now, and I didn't really need to upgrade my CA software. I don't have strong commercial needs anymore, so I bought the Home Designer 2022 software instead of full commercial C.A. primarily so I can be my own client. I didn't realize there would be compatibility issues. Home Designer allows me to open my old C.A. files but does not allow me to work in them. Technical Support said I can fix this problem if the file can be opened in Chief Architect, R13 or earlier I think she said, and saved as a Home Designer file. I don't know where my UBS access "key" is to utilize my old C.A. software.. it's been a few years.
I have a single file that I'm hoping someone can open and save as a Home Designer file. I confirmed that this is not against any laws or C.A. rules.This is my first use of this forum. I will check back later today, assuming it's not okay to put my contact info here. Your help is very much appreciated.
Thanks, Rich Kenney
