I just ran into a problem with NetGroup.Connect.Rejected, my FMS4 server was running ok – I have even tried Cirrus/Stratus and I was still getting this error on demos, which were properly working before.
OK – so what is this error about?
It’s all about your Flash Player security and it’s basically telling you that you have denied access to some source. This happens, when you start developing apps on different PC and someone before you denied to use P2P or similar.
1. Go to Global Settings
2. delete all or specific P2P settings in Global Settings
3. run your application again (it should be in browser, had sometimes problems with standalone apps, where dialog didn’t appear)
this dialog should appear. Click Allow and better Remember.
Don’t forget that these settings are inherited to all versions of Flash Player you have on your PC, even to betas or prereleases.
