Error whilst downloading

Hello! I've tried 3 times to download the free version and get the following:

NSIS error

The installer you are trying to use is either corrupted or incomplete.
This could be the result of a damaged disk, failed download or virus.
you may want to contact the author of this installer for a new copy.
You may be able to skip this check by using the /NCRC command line switch. (NOT RECOMMENDED)

Please advise?
