Ive registered, do I need a fresh copy of the blockchain? Or its fine

Nope, You dont need to download the blocks again.
If You have saved them, You can run the new wallet...

Perfect man great work

I still have the 13k you gave me and buying more

Guys it's need to download the blockchain, to ensure the correct operation of the block explorer.
So as I wrote earlier:
