Just purchased the unlimited generator version. Followed installation instructions (both in the included pdf file and the online version). Uploaded and extracted everything. Created the xml files and set permissions on the files (666) and the "generator" folder (777).
Went to mysite/generator (also tried mysite/generator/index.php) to kick off the configuration process and this is what I get in the browsers (FF 6.x, IE 8.0 ):
Internal Server Error
"The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, <replacedemailaddy> and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
I have not modified any of the files in any other way.
