Already done...nothing to see!
nothing to see where ?
is your balance in block explorer exactly the same as in your local wallet ?
But maybe you can help me with that rescan...it sounds like it might work!
if explorer shows same amounts for all your addys then nothing is missing actually, they simply don't exist.
there's rare possibility that you lost private key(s) somehow.
try -salvagewallet
I know exactly that i have bought 10000000 of html and i am sure that there are 750k missing...there was no transaction and i havent lost any private key! like i tell you...they was missing from one day to the other...simply gone!
and where do i try those commands? like...where to write -rescan or -salvagewallet so it works?
if you know, then there are tx-es in explorer that show how you sent them into your wallet,
and then every tx that make any change, they can't simply vanish.
it works as normal command-line options
e.g. htmlcoin-qt.exe -rescan
Of course i know about the tx-es but i had the 10000000 already there for a week or two and everything was ok...and all of a sudden it was gone!
and the other thing is...no offense but for you its easy to say it works as normal command-line options...but i have no idea what you are talking about
sorry i know you want to help and am really thankfull for your time...but you have to explain it more easily...like you tell it someone who has got no idea...like me 
so how do i rescan my wallet?
