Hi all,

I have lost access to my 2011 account which has over 4000 posts.  When I try to get my password back, I get messages that my email address is not recognised even though I have old emails from noreply@bitcointalk.org relating to that account in my inbox.

Who can help me resolve this?

BitMaxz and TryNinja - I have no idea how come Windows 10 offered me testnet instead of the live client on start menu but you are both correct and I'm very grateful.  All working again - thanks.

When I try to create an address to recieve BTC, the Bitcoin core client seems to work fine but creates addresses that are invalid.  For example: 2NGMDeJdpn1TStxeA5EcdfHy4t2jDqrv3Pa and 2NA1gSNsMBmtSRLJTU8dB9AMrgF2vMmsVMd

Also, it has lost some addresses that I created yesterday.

Can anyone help?
