Fantastic response time maybe, but at least one of the issues persists. I have been attempting to download the latest version for some time now. End of last week, the download would perennially terminate with "Download verification checks failed". I decided to let the problem settle for some time, figuring it may be fixed by some time this week. I retried last night, and the download went smooth until about 1 GB, when I had to shut down the computer. I resumed the download this morning, and it terminated with "File downloaded is smaller than expected" after a short while.
I uninstalled Elemental, "Reset data" on Impulse, exit and relaunched. It was still showing the download of the update under "Downloads", asking me whether I wanted to resume (I thought that had failed???). I canceled it. Now I have the option to download version 1.09e (without "Show prerelease versions"), or 1.09n (with "Show prerelease versions").
To be continued when I find time to reload 2.2 GB (my provider cannot provide; at least not anything faster than 1 Mb/s out here in the boonies)
