V3.0.16.295 of CFWP has driver conflict with perfect disc boot time defragmenter

Upon updating to the latest version (using the built in updater), the boot time defragmenter from perfect-disc (www.raxco.com) would not run due to a driver conflict. Upon reverting back to the current version of comodo FWP using acronis, the issue disappeared. Obviously there is a driver conflict with the comodo firewall. Another issue: the proactive defense will cause windows explorer to crash while erasing files from the utility called ‘sandboxie’. This happens whenever I try to erase the files from the default sandbox. this occurs with all versions, when proactive defense is loaded with the initial installation. Will the current version I am using still protect my computer adequately? or, does anyone have a ‘fix’ for the driver conflict? Thanx.
