Got it, thanks for clearing that up.
I know what you mean, but my plan is to upgrade them. I've already cross browser tested, and customized everything throughout, so all is good. Takes me a week tops (but I don't do the Fast Lane Checkout mod) to fully customize a site - that's just coding AND adding content/pages and cross browser testing, not design concepts. I'm a bit of a workaholic LOL! (a geek really). Thanks for your help!
Just realized too that I couldn't have downloaded the 4.1.9 files from my own licenses anyway (mine are newer) because they are not there. I just checked, and all I can download are Updates, no core x-cart distributions that old. SO, I just sent a message to them telling them they have to get their original developer to upgrade them from 4.1.9 or hire X-cart. I'm not going to be responsible for this one (they have some customizations involved)...
thanks again!
