Cant Install

Sorry about that , but i have the Bulletin Soft from a Sponsor and cant write in the offical VB Forum.

I have VB 4.1.0 and want install Proxy Alert, but every Time, every Version of PA says by the Plugin Manager : install plugin ... and i wait and wait, but nothing happens.

Every Time i must go back or renew the Browserwindow because nothing is done.

I have upload the File to the upload Directory in the Rootdirectory from my Website. Or, in the new Vesions of PA they are more Files and a Dir , i uploaded all ...
I dont know ... Does the Instatfile (XML) not find the proxy.php (or in the newer Version the other Files) ? Is this Mod not compatible with 4.1.0 ?

Please, i dont know what the Error, but i must excluded the "Proxyusers" from my Board.
