the Lightwallet is outdated and doesn’t get any updates anymore.
While it is still working, one issue is that the nodelist isn’t maintained anymore either, which makes it hard to find a working node.
That said, if you still wish to keep using the Lightwallet regardless, you can try this:
Tools > Edit Node Configuration > Custom > put this in the empty field below: https://perma.iota.partners:443
Log in with your seed and if your balance isn’t back yet (because of snapshots), go to the Receive tab and generate and attach as many addresses as you’ve used before.
You can also just switch to the new Trinity wallet by simply logging in with the same seed you’ve been using with the Lightwallet.
You can download Trinity wallet from here: https://github.com/iotaledger/trinity-wallet/releases
Pay attention that you get the correct version for your OS. There are two separate versions for Windows.
First thing you do is go to Settings > Node, disable all options except "Use remote node list" and select this node from the dropdown list: https://perma.iota.partners:443
Then log in with your seed and make 1000% sure that it’s really the correct seed without any typos and such.
If you've noted the checksum of your seed at creation, pay attention and see that it matches.
If you can’t see your balance right away after login, go to Settings > Advanced Settings > Snapshot transition.
Let me know if you run into any problems.
