Thank you very much I think it's because my laptop can not handle the computing smoothly，maybe I need to upgrade my hardware

Thank you first. I don't know how to describe the drawing,but...fine, i would not edit that drawing again, I think my cpu can not compute the operation. I'm a student from China, and it maybe my first time to post on a English forum, so please forgive me if i use the wrong word or grammar :lol:

Uh......I don‘t know if it is the software's problem or my laptop's problem, but when i open a 'complex' Eps vector image，my AD gets slow and i can hardly operate it, and, when i open the same file in illustrator, there is no such problem. my laptop is Dell inspiron 5548，windows 10(build 10586)，8GB RAM. and that 'complex' file attached. 57316ad78eed3.eps

Thank you very much, i will try again Aha！there must be something wrong with my downloader, and i tried to download it directly using chrome, and i get the right version now.

I wondered why I clicked the download link you provided, but I get a installer 1.5.0.2? My location: China Sorry my English is quite poor.
