I notice a couple problems... One the Geforce 8800 Gt has 512Mb of memory so to start we need to adjust your hash per thread ratio. the default count of 8x40 is 640Mb worth so lets lower it to a number your card likes..
Also the SMX factor is 14 for that card, so I think your second number has to be divisible by 14

add -l 7x28 to your startup batch file or configuration. (that is a small L not a number 1 or a letter i )

Another problem or oversight.. not sure which...  your address is incorrect.. if you want to mine QCN you need to go to port 45570 not 45550

also just go ahead and omit the -a cryptonight since it is redundant if you are using the cryptonight only miner software


example: ccminer -l 7x28 -o stratum+tcp://qcn.pool.minergate.com:45570 -u yourmail.address.com -p x

I hope this helps
