Arduino software loading problem.

I was using the Arduino IDE program when I had to reload it for some reason. Now when I load the software I keep getting the same error message, "could not load keywords.txt. please re-install processing." I have tried the old and the new programs from

No one seems to know the answer?

Any ideas? I am using Windows 8.

Make a fresh install.

Do you have Java (or parts of it) on your computer? Try to remove everything. Keep the folder with the projects and the extra downloaded libraries, but remove the Arduino software as much as possible.

Download the Arduino software and place it in a new folder. Run it from that folder. Try the blinking led example.

Is your harddisk bad ? Perhaps you can run a harddisk check/verify.
