Not the OP, but I think I'm having a similar problem (talked to you in chat last night). I went ahead and left it running overnight and I'm still at 5 years to go. It's the same PC where I'd just updated a doge wallet, and that went way faster, so I'm assuming *something* is wrong, but maybe it's just slow like that.

I downloaded the April 2021 bootstrap that doog linked, and dragged it into the appdata/roaming/clam folder (if it's supposed to be in a subfolder in there, maybe that's the problem, but I read the post as saying just put it in that clam folder.

The bottom left does say "importing blocks" like the post said would mean it's working, so IDK.
