Is the orginal starcraft screwed on Blizzard store? or whatever its called

Trying to open up orginal Starcraft and in simply dosnt work…(It worked a few weeks ago) Is this another Activision decision to make us buy the remaster?

Whenever i try to launch its an update, but Woopsie, there was a error…

Just tested it, it works fine for me least but I also recently installed it.
