hi - Whever I start the PeskUpdater tool - or the PleskAutoUpdate tool in windows explorer or through dos or the start menu I get the following exception below. So it seems that I haven't downloaded and installed any of the hotfixes for Plesk 6.5. I have manually installed a necessary hotfix to install the backup utility, which is also now installed. But I'm now trying to run the backup utility which is giving a similar .Net error. (though i can backup domains through the Plesk control panel - is that using the same utility?) Anyone got any clues? Is it a configuration error in my setup of Plesk, or is it a conflict with .Net? Or anything else? Any help would be great! Thanks, Chris.
