I told you to create one post on a community forum and you went and created 3. 2 here and one on reddit. You know the same people frequent all community sites? Making multiple posts doesn't help anyone.
I have never created any post on Reddit... Bitcointalk forum is the second community sites I have posted, after StackExchange.
You validated the pgp signature when you originally downloaded electrum and created that wallet? I mean 3.1.3? Do you remember doing that?
I remember using the exact electrum exe file because that file is the only one exist on my computer, and I have created the wallet around May, which isn't that long ago. I have validated the file today.
Then the keys are at least somewhere in the wallet file... Providing you did definitely verify the signature the wallet was installed iwth.
That is the weird part, I am sure that I have made enough research before downloading the Electrum, and validated the signature today, nothing seems off. Note that I am using portable version so it might not be as safe as normal installer.
Tried what on bitaddress.org, I hope it was offline?
Try if the private key match the address with balance, but bitaddress.org told me I am wrong. And yes I downloaded the html and do things offline.
What is the balance if you don't mind sharing it?
Not much, but still an important fund for me.
Could you send me one of the signed messages to check it definitely signs from the right addresses (you can do that via pm)?
I will send one for you, but I have checked several times and conclude that the private keys simply are wrong.
