I'm still troubleshooting and not sure what is going on. KMM compiled from source about a week ago worked fine this morning. I compiled a fresh version and started getting errors. The initial error was asking me to select a currency, which in my case is USD. I did so but when I opened my file most accounts were zero with no transactions.
I tried switching back to the previous good version but it asked the same question when I tried to open my file. I verified that my KMM file had not changed but kmymoneyrc appears to have changed. I have lots of backups (thank you syncthing) and will let you know if I figure any more out. *----Brendan Coupe*
