Plug-ins problem - Move Unauthorized Plug-ins [SOLVED]

[HBHH]

Hi all,

my system ran fine for nearly a year, but since yesterday, if I start Pro Tools 9.0.6, a dialog box will open and give me the following message:

"MOVE UNAUTHORIZED PLUG-INS
Pro tools could not load the following plug-ins either because no valid authorization could be found, the ilok key was not connected or the plug-in was damaged:

BF Essential Clip Remover.dmp
Bombfactory BF76.dmp
Chorus.dmp
D-Verb.dmp
Dynamics II.dmp
Dynamics III.dmp
EQ II.dmp
EQIII.dmp
Flanger.dmp
Funk Logic Masterer.dmp
Invert-Duplicate.dmp
LoFi.dmp
Mod Delay II.dmp
Multi-Tap Dealy.dmp
Normalize-Gain.dmp
Ping-Pong-Delay.dmp
RectiFi.dmp
Reverse-DC Removal.dmp
SciFi.dmp
Signal Generator.dmp
SignalTolls.dmp
Time Comp-Exp-Pitch Shift.dmp
Time Shift.dmp
Trim.dmp
VariFi.dmp

Move these plug-ins to the "Plug-Ins (Unused)" folder? Y/N"

If I click "NO" - Pro Tools 9 opens, but the plugins are gone. Yet I still can find them in the Plug-ins-Folder.

As far, as I know all of these plug-ins are free and included in Pro Tools 9.

What has happened? Any solutions?
Thanks in advance!

SOLUTION:

Problem SOLVED!

First thanks for your help Chris. I tried out your suggestions, but the first ones didn´t help:

"Update your ilok drivers: www.ilok.com

Trash all pro tools prefs....

Go to Users > “your user name” > Library > Preferences....
-Delete 'com.digidesign.protoolsLE.plist', 'DAE Prefs' (folder), 'DigiSetup.OSX' and 'Pro Tools preferences'. "

Before reinstalling Pro Tools 9 - I took a last look at the Plugins Folder and mentioned, that all the plug-ins that didnt´t work were located in subfolders.
For backup-purposes I had copied all the plug-ins before. Through this process the system had asked me for my admin-password (I wondered about that). Well after backing up the plug-ins I didn´t have any subfolders in my backup-folder, just plain .dmp files - even from those plug-ins that had been in subfolders before.

The solution now was to delete the plugin-subfolders in the original plugins-folder and replace those plug-ins with the plain .dmp files from my backup-folder.

Everything´s running fine again

Thanks again!
