Hi All
I am sure this post must have com up before but i cannot find it anywhere.
Arduino was....... working perfectly happily and doing everything it should with no problems then i started getting the odd message 'Cannot Load Keywords.txt re-install processing' when i try to open an arduino file (*.ino) this happens on all projects. At first Arduino carried on opening, then later it came up with the message then closed again
First step uninstall and re install Arduino to the lates version....... same effect
Next i know Arduino uses Java so uninstall Jave and re install to latest version.... same effect
I found a post in a forum saying that there was a Keywords.txt bug with a copy of what it should look like so replace Keywords.txt ........ same effect, Arduino starts to open, the killer message then closes
I'm starting to run out of hair to pull out, as i said before i'm sure it must have been seen before, is there a guru out there that can help PLEEEEEEEESE
oh one other thing there is no problem with the project files, they open fine on a different pc
My system XP SE3

thanks for any replies
Dave

Hi, I've never seen that problem but files named keywords.txt are associated to libraries -- both the Arduino core libraries and the user-installed ones. Since you reinstalled the Arduino software I would look into the libraries directory in your sketchbook directory (the default location for your sketches and libraries, usually somewhere under your home directory). You may try to rename it and create an empty "libraries" directory, see if the sketch opens, then move the existing libraries into the new directory until you find the bad one.

Hi, Thanks for your input. the weird thing is that all of the files work ok on a different computer. The clue (i'm starting to think) might be in the bit that says 're install processing', i took it to mean base programmes i.e. Ardruino but after chasing down the processing bit the Arduino front end looks remarkably like the graphics programme called processing front end i'm wondering if the error message i'm seeing is a left over from the conversion from processing to Arduino.
i did try what you suggested, deleting and re creating the base folders but still get the same problem
weirder and weirder...... got to be something simple, looks too complicated not to be

Hi, I just got the same error (intentionally) by deleting the file libraries.txt under the Arduino program directory (on a Mac is <arduino-root>/Contents/Resources/Java/lib, on Windows I believe that 'lib' is just under the arduino root directory). So I would reinstall the Arduino IDE one more time (and check that any arduino-related paths, such as those used by the "Open/Open with" commands, point to the new installation).
