I've had my MacBook Pro Mac OS X Version 10.7.5 for 2 years now, and suddenly none of my Finder windows will display any files, and it just appears as "Window" with no options and just a blank screen. I've tried re-starting, I've tried trouble shooting, I've tried anit-virus, I've tried safe mode too, but nothing seems to work. Is there a way I can fix this without going to Apple support and paying 20 dollars for them to fix what could be a simple problem? Edit Oct 20 2013: The Kill all command didn't work. The $20 is from the support guy who wanted to remotely troubleshoot my computer. I have have tried doing it on a "Test" account, but to no avail. The same problem occurs. However, when I upload files and such, as I did in the images below, I was able to view them just fine. However, the Finder windows just seem to keep not working. Eureka!!! Viola!!! Thank you priitv8. I did a recovery from partition, and the disk utility verification, but that did not work. However using the recovery partition I updated, my already updated software in hopes that it would have deleted the corrupted program and put in the exact same, but uncorrupted on and it worked! Thank you for helping. All of you.
