Fifty days ago I've donwloaded Ethereum Wallet into my computer without letting the wallet to SYNC and download all BLOCKCHAINS because it took about 4-5 days and it is still not synched, anyways I've bought 8 ETH and scanned my wallet and it's there.
Currently I received a computer which is way better than my own and finally installed the Ethereum Wallet again and synched the wallet at last so I can see my 8 ETH without scanning online.
The problem is when I installed the Ethereum Wallet 50 days back the app requested me a PASSWORD wich I didn't know it will be linked to my main account (I thought it was a password for the ethereum app).
So now in the present day, I have my wallet with all the ether in it but I can not move it to bittrex platform without the password.
The interesting thing is I have written down the passsword but does not match and I think I've a problem of a LOWER UPPER case letter
I only have on a USB the KEYSTORE FILE (UTC-xxxxxxxxxxxx), but I still have the Ethereum Wallet on the laptop if there is any file I might need from it.
Is there any chance that the password I put in my laptop without synching, did not reach the system, so therefore I have no password?
What can I do?
