Hey. I'll get right to the point. After having had an extremely frustrating time downloading the demo, (the download kept stopping, and I had to manually tell it to continue.), it's finally finished and upon double clicking the install file, I get this error message:

"NSIS Error.

Installer integrity check has failed. Common causes include incomplete download and damaged media. Contact the installer's author to obtain a new copy."

...And that's it. Does anyone have a clue why this happens? Could someone please help?

Thanks.
