Trying to upload the new tntfs.zip driver following the ZCM 11.4.1 Imaging Driver Update for December 2015 patch

When trying to apply the uploaded tntfs.zip we get

"Checksum of the uploaded Tuxera NTFS driver file does not match with the expected checksum in the NTFSDriver.conf file"

I have checked the updated

D:\Program Files (x86)\Novell\ZENworks\conf\preboot\NTFSDriver.conf and it matches that of the Dec 2015 patch

driver_checksum=f74288ecd4a474c8d7c6637f596ddf76

I have run md5.exe against the tntfs.zip we have downloaded from the above url and are trying to upload into zcc and the checksum matches....

Any ideas?!?

(Failing that can anyone confirm the tftp substrucure for the new tntfs drivers? i.e. does it change to 11.4.1 or remain 11.4.0)

Cheers
