Please help me.

I've tried to transfer my wallet*(*.dbixwall file) in another computer and my wallet is not showing up. I get a message "Wallet succesfully imported" but my accounts list is still empty.
And one more thing, when i want to send from pc wallet to livecoin i get this warning: Address checksum mismatch. Use only properly checksumed addresses to prevent wrong sends.
Today my DBIX wallet (DbixWall-WinGUIv1.0.1_49-2) do
NOT show my address. Yesterday was working fine. I also import my backup file (*.dbixwall file) and then get a message "Wallet succesfully imported" but my accounts list is still empty.
Anyone help me!
Create new account first than import and restart the wallet or restart the PC.
