What is the problem with Adobe Creative Cloud Premiere Pro CC 2014, why it freezes often?

Question

I Purchased the Adobe Creative Productive Premium Suite CS5 in early 2010 and I was very satisfied with it all this time, I can say that I never had a problem while using any of the Production Premium applications. Few weeks ago, I asked Mr. Philip Bloom about a technical issue regarding the best method to use a 50 FPS clip with a 23.976 FPS project, and I got his kind help but he recommended me too that I should upgrade to the latest Adobe Cloud CC 2014 which has many new features added to the different programs. I took his kind advice and downloaded a trial version of all the Adobe Cloud CC programs which I use for my filmmaking business.
Today is the 20th day of my trial period and I have 10 days left to take the decision of continuing with CC 2014 or not. The past 20 trial days were not very pleasant. I want you to share with me the following details which I'll list them as bullet points and I would appreciate diagnosing the problem if you can and suggest a solution for it  to re-try the Adobe Cloud CC 2014 for the 10 remaining days with no further problems.
I used to have the Gigabyte graphics card GTX 470 for about 4 years and it malfunctioned last year and I replaced it with a humble Geoforce GT 610 card, but it worked fine with the Adobe Suite CS5 programs.
My system configuration is Intel Core I7   950@  3.07GHz , installed memory 12 GB. , Windows 7 Ultimate, 64 bit Service pack 1, 3 hard drives 1TB. each (one of them is dedicated for Adobe asset files and the editing work)
For the first 2 or 3 days I used mainly the Premiere Pro CC 2014 establishing short projects for a max. of 5 minutes each and it was working normal. But, later, as soon as I started to build a project which reached about 24 minutes of length and I began to edit those before I add more clips to the timeline, unfortunately, the PrPro CC 2014 started to freeze on any of the frames every time I try to edit normally as I used to do with the CS5, so, I had to wait for 2 or 3 minutes every time it freezes, then it works for seconds then freezes again!!  and during the 20 days mentioned above it crashed once.
The movie files of my project are the Nikon's .Mov files and the editing work which I performed included effects such as Color correction (levels) color correction (fast) color correction (Auto) sharpen effect, and stabilizing effect.
I installed the Magic Bullets Suite trial version, and the Neat Video trial version, aiming to purchase either the DeNoiser or the Neat Video (but I tried their effects without saving them to the project).
I used to export parts/ or whole project before finalizing the editing process to be able to monitor on a TV screen (mp4 file format) some of the changes I made in PrPro before being freezed.
Based on my previous 5 years experience using the CS5 Suite I have a strong trust in Adobe, I never thought the problem was in the PrPro application, but rationally I thought it was the graphic card (GT610), and accordingly I purchased yesterday a new Zotac Geoforce GTX 770 (listed by Adobe as an approved card) and I installed it and checked that it is running fine and I checked the processor temperature which was within the normal level.
Only today, I began to think that it might be something wrong with the Adobe Cloud CC 2014 ( a bug or something) and as a result of searching on the internet I could see lot of users since 2014 who were having freezes and crashes with the CC and the CC 2014 versions. That was a shock for me, could it be that until Feb. 2015 the same severe problem still occurs???
Sorry for any inconvenience, looking forward to seeing a solution for that serious problem.
