When I press on proceed I got this error on Magento Connect :
Invalid Post Data
The error appears when you try to send the form through _GET (or to much data send through POST). This code can be found in downloader/Maged/Controller.php: (connectPreparePackagePostAction and connectInstallPackagePostAction methods)
if (!$_POST) {
echo "INVALID POST DATA";
return;
}
Check what the $_POST variable looks like. Also check if you are not over the post_max_size limit with what you send.
it might also be a badly worded error message. they use the same error message if you have an invalid form key. log back into the admin and then click the magento connect manager
In my case it was related to recent change in my .htaccess.
Thanks to this website (http://www.ecommerce-northern-ireland.co.uk/magento/upgrading-magento-via-magento-connect/) I now switch between 2 .htaccess files (optimized and normal) and it works perfectly
