Unfortunately, the solutions by reference did not help.

proposal to create a new wallet. maybe the problem arose because before that I used and updated the portable version and this time installed through the Windows Installer. I used to update an empty wallet. and for the first time decided to update in a hurry non-empty.

I used my wallet every day. Updated yesterday, decided to upgrade because transactions with high commissions took a long time and thought that the update would help.

In the wallet there is an inscription about updating, through this inscription I was updated.
The wallet is about 5 years old and I was updated not for the first time, the seed was recorded 5 years ago and lost. I know what does not delete, because I did it before and everything was ok. But now such a problem has arisen. The search certainly did, but he did not give anything.
Mb i should reboot comp....

I apologize for my English - google translate
Have a problem. OS - Wndows 8.1.

Electrum 3.3.6, on it I installed and named a separate wallet to receive and issue addresses 3..... after updating to 3.3.8 the file disappeared. I searched in C:\Users\username\AppData\Roaming\Electrum\wallets there empty. Seed is lost. did not make backups. I remember the password, of course, but it makes no sense because I can’t enter my old wallet. I can not find this file. I'm desperate. I tried to use Recuva to recover deleted files, but it does not find this file in deleted ones. I don’t restart the computer so that the RAM is not cleared, maybe this will somehow help in solving my problem. Before that, I updated the wallet and I do not remember that there was such a problem. Please tell me how to solve my problem and is it even possible. Thank you very much in advance.
