Latest dev is stable, that error you faced lived only a day or two days and was a little mistake to add some scripts to a wrong place Fixing it without an update was possible easily.
Starting from over or just updating is up to you … Both possible since you are at the beginning and trying to get it working and learning, but later your only chance will be an update So try updating first to get used to that (which is only uploading and overwriting though but may need some special operations depending on the update).
PhpVms v7 is not yet published or released, this is why you have only some beta releases and the latest development build. You can of course stick with latest dev and do not update it for a long period of time, what you will miss is possible new features and/or bug fixes etc. And if you follow basic procedures, updating the application does not affect your changes and or theme. So why keep yourself from using always the updated latest build ?
Anyway, just follow some guides, use theme duplicating procedures and have your own theme files and keep your visual changes safe from updates. This way you can easily update your core application without any hesitations. I am not here to force you to do some things, but believe me, importing data directly to database would probably give you more headaches and will lead you more bigger problems when you think that all is ok. This is the main advise, the main developer and us (users/3rd party developers), we give to new users … Do not mess up with the database unless you really know what you are doing and what will be the results on v7 core code.
I do not know how was the VAM data, if it is really in a shape matching all phpvms requirements then it may be fine, I do say ‘may’ because it is really risky What was the problem when you tried to import an airport, was it not found , was the icao correct, does that airport had all necessary fields in the csv file for import etc etc ? I kindly suggest importing flights though, phpvms v7 will add necessary (missing) airports to your database, no need to have all world airports there in the beginning.
You can read my guides about this logic too 'cause right now I am just repeating myself about things I already wrote and all is open publicly.

( 2 pinned topic here too , even though you do not use any of my addons, that theme duplicating procedure explained there applies to all themes including default )
Hope you manage this out and have a working v7 copy soon
