Is it syncing currently or just stuck at "11 weeks behind" status?
Yes, stuck at "11 weeks behind"
Delete everything from %appdata%/Lux directory
except wallet.dat, download latest bootstrap
https://bootstrap.luxcore.io/bootstrap.zip and unzip it to /Lux, run your 3.0.4 wallet
I first downloaded the Linux binary lux-qt, and it had this error:
./lux-qt: error while loading shared libraries: libminiupnpc.so.8
So I ran "locate miniupnpc" and found it here "/usr/lib/x86_64-linux-gnu/libminiupnpc.so.10" which is a newer version so I downloaded the lux source to try that.
I built the Lux wallet from source on Ubuntu 16.04.03 64bit lux-qt version v4.0.0.0-587beac
I'm stuck at 12 weeks behind, I copied the bootstrap.dat file listed above to my .lux folder.
It started and said something about "importing from disk" for only a second or two, then went to syncing with network 12 weeks behind.

I am thinking its choking on the bootstrap.dat file and stops.
Next i'm going to delete everything in .lux and try it without the boostrap.dat file again.
EDIT: I restarted the qt wallet after I deleted everything from the .lux folder and it syncs until block 1154 and errors out again and is stuck at 12 weeks behind.
