Hi, I know this is really not too much to do with Pentax, but last week my six year old DELL suffered a terminal hard drive failure. I had been having problems with slow screen regeneration and the odd report about memory addresses that could not be read, so I was aware things were not good. Fortunately, I had backed up my data files, both work and hobby, but I lost all of my programs. It took about four days to re install everything and get the configurations setting how I had it before, but now I am back on line. The new machine is WIN 7 with a solid state C:\ drive and plenty of RAM, so at last I can make the most of CS6 and the NIK package. With Adobe now on CC (Cloud Cuckoo?) I am going no further with it. If any of you are a bit hap hazard about backing up, take a warning from me, because the failure was sudden, it just would not fire up. No second chances. By the way, I have had to re calibrate my screen, which hadn't been done for several months (Lazy or too busy?) but I had not appreciated that it had been slowly drifting and some of my latest creations have had to be revisited. Another little gem to remember now!
