Every time I try to apply the Simox unlock patch I receive the following error.

New block #0000 added: $45100000
Blocks selected OK. Reading blocks: 1
Block @ $45100000 read error. Have only: 00000000 bytes

or

Blocks selected OK. Reading blocks: 2
Block @ $44140000 read error. Have only: 00000000 bytes


Can you assist so that I can remove the Network lock?
