My third party applications keep de-activating. How do I fix this?

Question

Hi everyone!
I am wondering if anyone can be of help to me. I am desperate.
I upgraded to Mavericks and am currently on version 10.9.5.
I have numerous third party applications...to name the two important ones,
most of them are video effects from New Blue FX and the other ones are just like converters etc.
I have had no problems with them in the beginning when I upgraded to Mavericks and
certainly no problems before Mavericks. Now all of a sudden, every time I try to use
these applications, it keeps saying that I am running on trial version and that I need
to activate the product with the activation code. This has never happened before and
it certainly has not got to do with a certain app as it is happening with all my applications
that require an activation code. I have to keep activating the apps everyday so that I can
use them and it is becoming really annoying and I don't know how to fix this.
I am sure it is something simple as my computer has been absolutely GREAT since
I have updated to Mavericks. Everything has been so much faster and just amazing until
this new problem. This is the only problem I have. I have checked and I have done ALL updates.
I am a video editor and I use Adobe Premiere Pro CS6 and these continuous activations are
really not helpful for me when I am trying to concentrate and use my effects.
But like I said, it cannot be just the effects I use for adobe as applications that
are not associated to adobe at all are being affected as well.
If you guys could help me, it would be greatly appreciated!
I am really desperate! By the way, I am working on an iMac with Mac OSX Mavericks 10.9.5.
Thank you so much!

Answer 1

Back up all data before proceeding.
This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Triple-click anywhere in the following line on this page to select it:
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
          Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
           ▹ Restart
from the menu bar.
