Factorio won't run

[robotJuggler]

Factorio x64 0.10.12
Game starts fine, and loads the main menu. But then I can't get into an actual game...
Load old game or load custom scenario -> ERROR: 'Player prototype required but missing'
Then it crashes and the program closes

Play -> New game -> Map Generator -> Generate: ERROR: 'At least one tile type has to be allowed'
I cannot proceed.

Play -> Start Campaign -> Box of scenarios is blank so I cannot proceed.

I've tried downloading a new version, uninstalling and reinstalling.
I have also reinstalled Java.
It used to work fine and I was playing it until a few weeks ago. Got all the way to Rocket Defense. Not sure what's changed during the break.
Any help out there???

Did you accidentally disable the base mod?

How would I have done that?

Ooo you're good. I deleted my mods folder and that forced it to download a fresh one. Works fine now. Thank you very much!

People reported this several times already, the game should probably give a warning when the base mod is disabled (added to our internal todo list).
