El Capitan and NTFS, re boot problems

Hi folks,

I updated my iMac to El Capitan and noticed that it no longer could write to my NTFS external hard drive. In the past I have used NTFS 3G and Mac Fuse. This worked fine with Yosemite, but clearly no longer worked with El Capitan. As a result, I bought Paragon's NTFS X V14 for El Capitan. The install procedure demands a reboot.

On booting I found I was stuck with the gray screen and the Apple logo, and empty progress bar. I left it for a while, but it seemed to be stuck. I the then left it for 2 hours and the fan was blowing, but no progress.

Re booting to safe mode didn't work, neither did re booting to diagnostics. The only thing that worked was the cmd+r to bring me to OSX Utilities. I went for the time machine to restore, it found the Time M and I was able to select a suitable date. But I got a usage saying - 'this disc can't be erased".

So; I went of to apple support, paid the money to talk to someone and we went through all the things I had already done. Boot + s, Boot + d, Boot+ cmd+r, nothing worked. This was waste of time and money. In the Mac OS Utilities I tried again but time machine could not restore with message saying 'this disc can't be erased". I did a disk utility and first aid on all drives, no problems were found. In desperation, but knowing I have an up to date Time Machine, I selected re install OS. I expected this to create clean install and then from that I could use my time machine.

I was surprised that after the re install my Mac brought me back to everything - as it was before. I uninstalled Paragon's NTFS X V14 and rebooted, but found myself back to where I was before - grey screen empty progress bar, refused to do a safe boot and so on. I had to start all over again with recovery and again it brought be back to where i was just before I rebooted.

This time I went to my time machine and selected the first date after my El Captian install. Everything is now working fine, but I am very reluctant to reboot!

Any ideas, suggestions!
