Hi guys, I just started using Electrum. I heard this was the best desktop wallet, however, versions 3.0+ won't open. Nothing happens, no error, nothing, it simply doesn't open. I downloaded version 2.9.3 and it worked fine.
Can I keep using 2.9.3 or is it unsafe?
If you're not getting any visual errors, it could somehow be related to the issue mentioned on their github repository over here:
https://github.com/spesmilo/electrum/issues/3290 and here
https://bitcointalk.org/index.php?topic=2395038.0. Try running the portable verison and test if that one runs fine.
It's very safe to use 2.9.3 until you've not converted your wallet to the new segwit format, which I believe you might not have since your application wasn't able to start, and when it did it'd have asked you for a prompt to do so. So, you can continue to use 2.9.3, and make sure you report your issue on their github page.
