Those having a problem with the Windows wallet BTCtalkcoin-qt.exe crashing, I had that issue as well.  My solution as follows seemed to take care of it.

With the wallet program shut down, do the following:

In Windows File Explorer go to the address: C:\Users\\AppData\Roaming\BTCtalkcoin
(Replace in the address line above with your Windows username.)

Delete ALL files from the directory INCLUDING the database directory.

Create the BTCtalkcoin.conf in this directory as documented in this thread, containing the following lines:
server=1
listen=1
rpcuser=user
rpcpassword=pass
rpcport=50554
addnode=108.61.103.155

Restart BTCtalkcoin-qt.exe.
