PortableAppsMenu Error Message

When trying to launch PortableApps from my falsh disc i get always two error messages:

1.
Window title: PortableApps Menu: PortableAppsMenu.exe - Application Error
Message: The exception unknown exception (oxoeedfade) occured in the application at location 0x7c59bc81

2.
Window title: Application Error
Message: Exception EOSError in module PortableAppsMenu.exe at 0000DA65.
System Error. Code: 87.
The parameter is incorrect.

I've installed the complete package without modifying anything.
I can launch all the applications without problem directly.

Where can be the problem?
Do I have to modify anything or...?

Thanks a lot for helping me.
