The second one gives useful information : 300bts

It's still a very little amount, but just an express of my appreciation.

I have wallet and private keys backup for bts 0.8.0, since than I have not touch.

Then in last year 2016, I found bts upgraed to 2.0, I downloaded  BitShares-light_2.0.160314, installed.
and imported private key, but the account value =0 !  (since it was cheep, so i didn't investigate further)

Recently, I know that first I should first  download BTS 1.0, version 0.9.3, than export wallet .
so I did.
1. exported wallet in 0.9.3.
2. installed BitShares-light_2.0.170522. and run
3. created account

but I can't found any import private key button or some control method on the screen.

Can anybody help.
If I can take back my account, I will give a little bounty 500bts for my appreciation.

Thanks!
