Thank you for contacting Presonus Technical Support. Sorry to hear about the recent issues you have been experiencing.
Please try to use a download manager to download the content directly from your My.Presonus.com account. These will help to optimize your ISP's (Internet Service Provider) download bandwidth to utilize the amount of bandwidth you have purchased from your internet provider, but will allow you to pause and resume the download should you need to shut your computer off or disconnect it from the internet. Two products PreSonus recommends are:
Use a wired connection instead of WiFi. If at all possible, a physical connection to your router offers the best stability. While WiFi has seen vast improvements in stability over the past few years, it is more prone to connectivity issues than a wired ethernet connection and will often dilute the bandwidth available for a download.
Download each file one-at-a-time. If you attempt to download all the content at once, it could be overtaxing your internet connection, resulting in slow downloads and instability.
Make certain there are no connectivity issues to your router or ISP (Internet Service Provider). If you frequently notice that your connection drops out, slows down, or causes web pages to not load, you may want to contact your ISP to address this issue.
Consult with your ISP provider and ask if they have larger download packages available. Many ISP providers offer larger packet download and upload sizes for purchase. You may not be aware that you are signed up for a smaller packet size through the ISP provider you use.
It is always a good to know the download bandwidth you currently have with your provider and upgrade should you continue to have issues with a smaller packet size offered by your ISP provider.
If the issue remains, please create a ticket to technical support.
