cant+open+saved+emails

a friend sent me this query as it was me who recommended him to eMClient…

Sometimes I save emails as files simply using the file/save as command on EMail client and then putting them in a folder. I noticed today that I cant now open them. The symbol next to the saved file has changed and looks like a tiny blue envelope. When I try to open it I get a blue screen with “First Things First, Let’s Add Your Account” and  a box with + Add Account. Opening this gives a list of options such as Outlook, Exchange, Google etc. Previously the file with the email just clicked open.

anyone else have this issue? It’s a win 10 machine running EM Vs6
