There is an incompatibility or something between Sony Ericsson Update Service and WindowBlinds (tested with v.6).
What it says:
"Application Error -> Incompatible Macromedia version. Required version from http://www.macromedia.com. Application will terminate."
Now maybe I'm not to 'skilled' at this, but there could be much more applications that could experience the same problem or even others!
*Note: to me and others, this appeared even if we had the latest version of Shockwave Player and Flash Player.
