I upgraded from DNS 10 for Small Med Practice to DNS 11 for Small Practice a few months ago. Now it won't launch and I get an error message telling me to reinstall DNS 11. When I look at my C: drive which is an SSD to boot up Windows and run DNS. I have a D: drive which contains an image and I keep everything else (as much as possible) on a separate E: drive. When I look at my C: Drive I see it contains both versions of DNS on it. Is there any reason I need to keep DNS 10 on it, does my DNS 11 use any of the files from DNS 10 or when I uninstall DNS 11, can I uninstall DNS 10 and not reinstall it to free up space on my C: drive. The manufacturer of my computer tells me the SSD drive will perform better if I keep it less than 50% full.  To summarize I really have two questions (1) Can I discard DNS 10 and not effect DNS 11 when I reinstall it? (2) Is it true that keeping my SSD less than 50% full advantageous? Thanks for any advice you can give me.

1 of the perks, that our customers receive, when purchasing their NaturallySpeaking products from us is our step-by-step pictorial KnowBrainer Installation/Training Guide which not only includes beginner, intermediate and advanced training but perhaps more importantly, instructions on the right way to install NaturallySpeaking which includes disabling the UAC in Windows 7, uninstalling all previous versions of NaturallySpeaking (before installing Ver. 11), NOT using your previous upgraded user profile and how to install your smart upgrade as a full copy. Simply put, there are a number of pitfalls that are easy to fall into and 1 of them is leaving your previous version of NaturallySpeaking on your computer.

1. Yes
2. We know that M-Tech stresses that you should not exceed the 50% full mark on your SSD but not everyone agrees with that philosophy. We have no experience in this area because our SSD is only 1/3 full so we are not qualified to answer this question.
