What version of build of Moneydance are you running on you old and new computer. e.g. 2019.3(1881)
Can you outline the step you have tried to load your account from Dropbox.
When you say account are you talking about your Dropbox account, your data set or setting up syncing.
Thanks for you help. I'ts now working on all of my systems. How I don’t know to be honest, I sync I thought with dropbox but have noticed that there is no files or folder in dropbox relating to monydance. Hay Ho leave alone if it’s working.
