I deleted the whole blocks folder. I have no blkindex.dat.
I can try getting that snapshot, but I'm not sure it would help since it isn't downloading any more blocks, unless I want to manually download snapshots for the rest of my life..
It got stuck like that on me a few years ago, after I used the snapshot I was able to sync. But I gave up on QT a while ago, blockchain is just too big, using electrum now. Anyway, when you say you redownloaded it, did you also remove all files from the appdata folder when you uninstalled? Wish I could help more but last version I used was .6 or something.
