File download mismatch

Trying to download new superbeam release (through program) but keep getting file mismatch.

Getting the same problem trying to download Prosteel 5.34c

For anyone who has this problem, if you have a relatively recent version with a 'Manual download' button use this - it bypasses the size checking, otherwise email me at support@superbeam.co.uk
