I removed Staxel from the Nvidia drop down and reinstalled it. It launched once and it worked, then refused to launch again after that. After the first successful launch, it just kept throwing up the red error box. It seems to be very hit and miss and totally random - once in a blue moon it will launch, the rest of the time it won't. Same goes for launching the actual world. When it did launch the one time, before it broke again, I created a new copy of my world. I also tried to create a completely blank world. None of the three worlds would launch - the blank one wouldn't even create. All worlds crashed with the same messages from the start of the thread. I tried a few times. If it helps, I'm running a gaming laptop and I have a dozen other games which all load and play first time, every time with no problems. I'm not sure why Staxel suddenly stopped working and why the fixes don't appear to be working either.
