You may have been tired and forgot to highlight the clips/clip. I have been using CS5.5.2 for 3 years and the only isue I have had is when I acccdentally got rid of the Sequence Icon, which gave no monitor or timeline windows ?
Have you installed the latest upgrades at least to .2 ? Have you cleaned up the Media Cache base ?

It turns out that when I have my second monitor active to show the timeline video, that is when I am unable to import or replace any media. If I disable the second monitor before trying to import, then I can import with no problem. If I enable it again, and try to import footage PPRO becomes unusable (freeze) and I need to force quit. I have beeen using a second monitor in this way for years and never saw this behavior before. Any way to avoid this workaround?
What is your exact brand/model graphics adapter (ATI or nVidia or ???)
What is your exact graphics adapter driver version?
Have you gone to the vendor web site to check for a newer driver?
For Windows, do NOT rely on Windows Update to have current driver information
-you need to go direct to the vendor web site and check updates for yourself

Hmm... that is a fairly "old" ATI card, and I wonder if a Windows Update changed "something" in the Windows display DLL's that is causing your problem, even with a newer driver
Not video editing, but my wife's computer has an ATI 5450 and she uses Win8 and a 3D Cad program for house design (our house is for sale and she is designing the next/last/retirement house we will will build when this one sells)
When I updated her computer to Win8.1 it TOTALLY KILLED the 3D part of her program... flat lines would draw to outline the house & rooms, the rendering of 3D images would no longer work (and, she also uses 2 monitors, which she would NOT give up) so I had to use my recovery software to put her back to Win8
Even if you are on Win7 it is possible that a Windows update is the root of your problem with that "older" card
