I reinstalled DN from scartch early this morning. I confirmed it using a virtual machine. My host PC has clean client running and my virtual machine uses the patched one with trainer. conclusion fresh install = NO DC while Patched client using trainer = DC every 5-10 mins. And this is not only true for sir Xkhen's trainer, antifoo's patch, as well as other trainers that some of my in-game mates are using all share the same problems. I don't intend to "blame it to the trainer" (specially xkhen's since I owe him and his trainer alot!) and I think most if not all the other people here using Xkhen's trainer has no intention of blaming it too. I believe the reason for reporting it here is for solutions due to the fact that we have confirmed it by testing. C'mon, we're suppose to be a community here so we report issues to sort things out and make things better. What we are looking into now is maybe sir xkhen would be kind enough to test it himself and look into the matter.
I hope this thing can be really sorted out. Farming DFB RC and EoL manually is kinda boring. ^_^
