I tried to play the HD version of this mansion, but couldn't start it. Is there someone who can have a look at this issue? Thx.

I took a look at it, and i was able to start it just fine.  Here's what *might* be happening. The download is a zip file that contains a README.txt and *another* zip file that is the mansion. You can't play the outer zip - only the inner one.

This is kind of like in the original game - sometimes mansions would be be archived in a directory of the same name. Sometimes not. Some designers would include additional files: text files, graphics, etc that they would want bundled together. So, all the mansions I "converted", I archived in a directory of the same name to accommodate any additional files that may be present.

Brell didn't use the same convention when he uploaded mansions.

I'm somewhat regretful of doing it the way I did, and I may still go back and change them to make them consistent - perhaps sometime in December. Unfortunately, far more were uploaded the way I did it.

Thx for your help Rob. It works fine now. :)
