Anyone else find Zamblek support useless?

So I purchased sngine and it came with Zamblek support, I can’t get the facebook registration/login to work, even after following the directions 3 times (I did twice, had someone else go through it once) even after telling them I’d gone through this already… they send me the directions again… if this is what I can expect from them, I don’t think I’ll ever buy anything that includes Zamblek support again
