Cannot play D2 after installing downloader

Sorry if this has been addressed in other threads, but haven’t found anything.
I decided to finally download Diablo II and LoD.
I have my old CDs so have the 16 character keys.
As described in other threads,
I went to my account,
to Download Games,
scrolled down to and clicked on Diablo II,
clicked on Windows.
While trying to download “Downloader_Diablo2_enUS” I got several “script error” messages. They looked long and complicated so didn’t write them down, and they didn’t stop the download.
When the download was completed I got the classic Diablo II pop-up window. The top most button was Play Diablo II. Clicking on this did nothing.
I’ll try again some other time and write down the script errors.
Otherwise, am I missing something?

Did you ever figure it out? I’m stuck at this as well.

Had a chance to try again.
Following are the script errors I encountered. I tried three times and the errors are the same.
The real errors have no spaces in the URLs, but I couldn’t post this reply without adding spaces.
