Sharing a database via Google Drive and setting up accounts
I'm fairly new to Filemaker Pro, so there might be an obvious answer to this, but...
We're setting up a database for our office (five people), we've got subscriptions for five users, but not a server subscription. The office does not have a LAN setup, we use Google Drive on a wireless internet connection. When we save the filemaker database in Google Drive and everyone accesses it all seems fine, but when you add data it isn't saved. I have tried to turn on sharing, but now every time I open the database the message "Filemaker cannot share files because another user is already sharing files from this computer" comes up. This is the first time I've had Filemaker on my computer, so I don't really see how there could be another user already sharing.
Is there a way that we can share and use a filemaker database without a local network, preferably via something like Google Drive?
Also, when I've tried to set up accounts people can't login to them. No matter how many times I check them or try different combinations, every time they try it comes up saying the name and password aren't correct. Is there something I'm missing here?
