I thought I'd give solo mining a try with this coin. After about 1/2 a day, I was super pleased to have found a block! Awesome.
The bad news is that just a few hours later, the block I found was ORPHANED.

It's not like the same block was solved simultaneously as mine, it was hours later.
So I'm pretty pissed at that and just about ready to drop Bytecoin. It's hard to have faith in the coin when basic things like this happen.
As Ahmed_bodi pointed out this is an effect of difficulty and the overall network condition at the moment. An unfortunate problem no doubt, but don't let it mean your ready to give up already!
My pool seems to have a pretty high % of the total network hashrate at the moment, and likely what happened is my BTE node did not recieve your solved block broadcast before the pool mined a block itself. If you are going to keep trying solo, add my node to your bytecoin.conf file "addnode=75.156.208.65" and this way the pool will see your mined blocks right away, and instead of continuing to work on one at the same height the pool will start working on top of your solved block and help ensure it's confirmed and stays in the block chain.
Hope that helps, and I'd be happy to help you if there's anything else I can do.
