First of all just so you know when working with magento connect it is not unusual that the maintenance.flag file appears and then you have to delete it to move on. 

Next, the extension..it looks like you need to contact the developer of the extension regarding the pkg file and the download. 

Hopefully by now you've solved this issue and this reply post is now just forum filler!
