not working!

always get this error at 99% of progress bar

Ensure that file permissions are correctly set-up – 775 or 777 to /xxxxxxx/htdocs/wp-content directory and all files and folders that it contains.

try to set 775 and 777 as the message said. waste time for 4 hours…decide to buy another plugin.

this plugin used to work very well a year ago…
