Hello,

This is scary.

I have exactly the same problem as you.

I was using the light wallet on ubuntu. I was using the version 2.1.

I entered my seed and the wallet showed 0 IOTA and no history....As if it was the first time i open this wallet.

I just have updated the wallet to the version 2.3.

Now i'm attaching adresses to the tangle.....hoping to recover my IOTAs.

Totally scary!!

It's not at all the right moment for this kind of issues 

Marcel
