I use version 3.02 . The original Wallet is very old, like 3 or 4 years, could it be that?

Hello,

i tried to send my Bitcoins from my Standard Wallet to a Segwit Wallet both in Electrum, but the transaction always gets rejected by the network. Is this not supposed to work?

Sry, i assumed the address was valid, because it was an Invoice Adress from BitPay. Turns out it actually is not. Seems to be a problem on their end.

Hi,

I can't send Bitcoins with Electrum, because it won't recognise the other address as valid, while i know for certain it is.
I heard this could be the case, because i still use an old address, that starts with 1. Could this be the case? If it is, what can i do now?

Thanks
