I'm trying to modify my invoices, quotes and so on, and have used the options page to locate and apply my logo, but when I preview or print any of the documents (invoice, quote, receipt), it doesn't show my name, address, logo, messages or anything else apart from the box with the details and amounts. When I try and look at the default template or even the custom one, the program says it can't find them. I don't know if the two are related. Any help would be appreciated.
