Okay, it sounds as if your graphics card is crashing from the asset. Could you please give a full make of the graphics card?
The asset requires a high end graphics card, though it hasn't been tested on AMD yet. Currently a GTX 1050 and GTX 980ti. The former being powerful enough to run at half detail, and the 980ti being powerful enough to run at full detail.
Also, could you please paste the errors shown?
There is a file labeled ESSENTIAL README which lists the steps nessisary, Though perhaps a video tutorial is necessary because there are a number of project settings that need to be set before it will work correctly.
Its also advised that you turn down the radius of galaxies visible setting, which controls the number of galaxies visible at once.
Also, ouch. One star review for the first purchase of the thing i spent 2 years making.
