i forgot disable DF first
What is DF?
and now i install again bitcoin on my laptop but the address show on bitcoin its new
Installing Bitcoin won't harm an existing installation but it is always a good idea to make a backup before upgrading the software, for instance.
my question if vendor sent bitcoin to my lost address is still i will have that money?
Just to make sure you aren't misunderstanding something ... your wallet doesn't have "an address" it has "many addresses".
Your wallet will hold many addresses, and you can still receive funds at a previously used address.
If you click the Addressbook, you will see your addresses.
