it sounds like you used the wrong bottom bracket it also sounds liek you are using the wrong terminology for parts

this is what I gleaned from you post
I had sg75 mounted on my bike today and I mounted the chainring the chainring seems warped and the chain line seems off

what brand is the ring what brand and model is the bb you are using did you mount the properly or did you do it wrong did you buy the parts second hand there is only so much one can do with out pictures and proper communication of the issue
