first off, props for mixing 90s tracks, and using perfect notes for pre-processing your tracks! That's basically what my primary use for Acid is.. with a goa trance tip! ;-)
Okay, crashing with ntdll.dll could really be anything, so that's a hard one to die down. I'd start with
running a chkdsk against your system drive (guide, option 2)
checking all drivers are up-to-date - specifically CPU, motherboard, GPU, audio devices
were you using any specific VSTs at the time - if so check for updates
Thank you Sheppo for answering my problem. I do not have that computer anymore and at Dell Inspirion 5770 i5 8250 U , 8 GB RAM DDR 4 I have no problem yet.Sometimes AP8 likes to turn off without a reason when loading a project from a file. I like music from the 90's and 80's and also trance :) And in AP I do things like that best :)
