I recently upgraded to Webbuilder 2008. All my file associations (eg. CSS, HTML, PHP etc.) are not working anymore. I thought this would be no problem. Simply right click "open with" and chose Webbuilder. But after chosing webbuilder.exe and clicking OK I can not select Webbuilder. It simply is not available.
Using the file association option in the preferences INSIDE Webbuilder is also not working.

Thanks in advance
