The advantages of keeping an Accounts file in iCloud would be if you wanted to have automatic syncing setup between two different Macs. We're still working on getting an iOS version out and when that's ready, that'll open the doors for syncing to those additional devices.
Now, regarding the updating to iCloud Drive, it's probably best to avoid doing that unless you're going to be using iCloud Drive on all of your devices as any changes made to an item in iCloud Drive isn't going to sync to devices using just iCloud.

It sounds you're encountering an issue that crops up related to Open panels. Can you Force Quit the application, if it's currently running, and try opening your data by double-clicking the file where it shows in the iCloud Drive folder (outside of CheckBook, in the Finder)? Let us know how that goes. If issues persist, email us at
support@splasm.com so we can send steps for gathering additional info that'll tell us more about what's hanging there.
