Land DD stoped working - license error.

I have a PC (AMD Athlon 64x2 dual core processor 3800+ 2.00GHZ - Windows XP SP3)

with LDT 2004 installed.

I tried to open LDT and the PC chrased while LDT was initializing.

When i started over the PC LDT begins with a message :

"The program cannot access a system file. To resolve this problem, remove any file access restriction and try again. If this problem continues, contact your system administrator or authorized Autodesk product dealer Error [16.1.7]"

i hit o.k. and get another meassage : "FATAL ERROR: The security system (softlock license manager) is not fun ctioning or is improperly isnatalled"

I hot o.k. again and then LDT init screen goes and LDT does not start.

I uninstalled LDT rebooted and reinstalled it (twice) but I get exactlly the same.

Somebody (thanks allen) gave me some more ideas so i tried and a speciall sw which fixes C-Dilla RTS (even i think that this was nothing to do with LDD2004.

Could anyone give me some help?

Thank you in advance.

John.

So what is the deal with this Softlock License Manager?

I don't know what this is. I just wrote the exact message on screen.

I tried several more things since yesterday.

I am afraid that the only solution will be HD format.

Did you create any Restore points prior to loading the software?

Is this the advice you followed?
