Region.exists: seems that imagefile could not be found on disk

what version? what system?
what exactly is the error?

... and the first question in those cases always is:
what changed between the last successful run and the first error situation?

It is the latest stable release of Sikuli 1.0.1. I am usnig Widnows Vista.
The exact error is the one I put in the title "[error]Region.exists: seems that imagefile could not be found on disk".

And as I mentioned the odd thing is that nothing actually changed between the last successful run and the first error situation.

thx

then run from command line:
java -jar <path-to>sikuli-ide.jar -d 3 -c -r <path-to>you-name-it.sikuli

take care, that no other characters than letters, numbers, hyphen or underscore are in the script path.

look at the debug output, wether something obvious is reported.

BTW: did you move the script to another place, that might have a "bad" path?

Ok so I run the debug as you said, and something did pop up, the enviorment PATH problem. I am pasting the debug report here, so do you think that anything could be done based on this?

If you do not have any idea about the error cause or solution, run again
with a Debug level of 3. You might paste the output to the Q&A board.

Thanks RaiMan, that solved my question.
