I've had Acronis since V10 and never was aware of any driver replacements. (They had Vxx numbers before they went to year numbered versions 2009).
The only problem I've had was the same one others had with a serial number. That problem was with the 2009 version, it was registered and working and then it came up with an invalid serial number. The fix was Acronis issued new serial numbers to those that needed them.
