Creating a new chain from Bitcoin 0.6.2

Hey everyone. I’m looking for someone who can assist me in setting up a new chain using version 0.6.2, keeping all the same configurations. Basically, I want to reset things on a private network. Do you think that can be done? I want to keep the same genesis block and settings (not the network settings since I’ll just be running it on a single client and attempting to mine). What do you all think?

Thank you. i compiled it but i dont know how to mine the genesis block. can you help me?

It's possible, after all there are few altcoin which created using Bitcoin Core (previously called "Bitcoin-Qt" and "Bitcoin") software. You probably should start by looking at guide which shows you to create altcoin by modifying Bitcoin Core source. And genesis block on Bitcoin is hard-coded, so there's no need to mine it.

But why else can´t i mine then a second block. Blockheight stands at 0

Without additional details, i only could make generic assumption such as mining software you use isn't compatible with Bitcoin Qt 0.6.2. Besides, what exactly you're trying to achieve here? I think you fell into XY problem.
