The multi file games might not work because the flash settings on your device don't allow the game to use the other files that the swf needs to load in.
In order to fix this you will have to replace the settings.sol file in your AppData folder. The specific path should look like this:
C:\Users\(user)\AppData\Roaming\Macromedia\Flash Player\macromedia.com\support\flashplayer\sys
But it might be different depending on your system language. In this sys folder you will find a file called "settings.sol"
You can rename this file to "oldsettings.sol" or whatever you prefer, this way you can always get your old file back if this fix somehow breaks something.
Then you can paste the "settings.sol" that is in this folder into the sys folder and now the games should work.

If this new settings file somehow ends up breaking something you can just delete it from the sys folder and rename the "oldsettings.sol" 
back to "settings.sol".
