Glyphs mini won't start on OS X 10.6.8

Hi, I wanted to start Glyphs mini after a longer time, but it said it is damged. “Delete and redownload from Appstore”.
I did that but now I get an error message saying I should upgrade my system. Error somehow is this here:

Dyld Error Message:
_ Symbol not found: OBJC_CLASS$NSJSONSerialization
_ Referenced from: /Applications/Glyphs Mini.app/Contents/MacOS/…/Frameworks/HockeySDK.framework/Versions/A/HockeySDK_
_ Expected in: /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation_
_ in /Applications/Glyphs Mini.app/Contents/MacOS/…/Frameworks/HockeySDK.framework/Versions/A/HockeySDK_

Any help? I cannot go away from Snow Leopard and it also should be supported from 10.6.6.

Thanks!

I have a look at it.

Thanks,

I already recovered the “foundation” file from an older backup but no change. Now I just upgraded to Lion 10.7. as I think this will still work for my older apps. I will test if it works now…

Ok, I cannot scan anymore now after upgrading to 10.7., but Glyphs mini runs after another delete and reload from the App Store. So upgrading to Lion fixed the obvious System Problem I guess. I wonder if any of my other Software is giving up now. Arghhh!

I still would be happy to know what happened here with the connection to the foundation framework. I should also mention, that I repaired permissions before dumping snow leopard .
Thanks Georg!
