Which version of Skyline are you using, and is it the 32 bit or the 64 bit version?
I thought that there might be a problem if the directory name contains chinese characters, although it works on computer even if I have a directory name like that. (That may because I am running Windows 10, and I think you have an earlier version of Windows).
Have you tried moving that .raw file into a folder whose name only contains English characters? For instance, if you name the file "D:\sop\test.raw"?
When you are seeing that error message, is there a button that says "More Info"? If there is, can you push it, and give us the rest of the info.
