You don't use a browser to download Native Instruments libraries. You use the browser to download the NI Native Access, which you then install on your computer. You then launch it and enter your account information. In the interface, you can enter a license code, but for stuff purchased directly from NI, it should how up automatically as a new available download or update. That's where you download Strummed Acoustic.

I also suspect that there are a lot of downloads going on with their 50% off sale, which may be taxing their servers.
