Flash apps "not installed"

Hello,

I have a problems with flash applications. None of them is working at all. In administration panel also i see "flash apps" not installed. How can I fix it?

At my side it gives the error: INVALID PARAMETERS

So anyone? I just dont understand why it isnt working on one of my servers. The main one. I had also installed dolphin on a localhost and another server. On this servers work great but on my hosting in justhost.com not. What I have to do to make this working?
