As others have said it doesn't work with current FM versions. I emailed and he actually sent me files so I could try to port to a more recent version of FM. I should try this but I got bogged down with other projects. For some reason it has gotten very slow, though that may be FM's fault - or more accurately the fault of running a very outdated version of FM on an OS it was not designed for. Billings is the only thing I have found that I might be willing to switch to but it's twice the price and I won't be able to import, probably, and I would MUCH RATHER stick with an updated BBI. But alas I think the prospects are slim. I think this is a pretty much abandoned app. Though ironically as I mentioned I have still gotten very good support, just no word on an update. I may bite the bullet and try to do a port, but if it doesn't "just work" I'm pretty lost.
