I will repeat the request in this thread:
The problem with Electrum, version 2.5.2 portable.
2.5.2??!? The problem with Electrum, version 2.5.2 portable.
That version is far too old... you need to use something like 2.9.3 portable which you can get here: https://download.electrum.org/2.9.3/
Don't try and use v3.x... it doesn't play nicely with Windows 7/8...
That is, do you think the problem is this? I should remove the entire electrum 2,5,2 and then just put a new one? And yet, 2,9,3 to put with 2fa or without, will not there be a conflict with the previous version? I have never updated myself and are not sure about the actions.
