This is probably a question for a Greenfoot team member.
Please remove your other discussion post on this matter. It is tagged incorrectly, anyway (Programming instead of Other).
I would suggest supplying your version number and your system information.
As a further suggestion, you may want to try removing and re-downloading the application.
@danpost
i did put it in programming but no one got back to me!
I have tried re-downloading it and that did not work
@danpost sorry I misread when you said about removing it from the programming category
@danpost ok I have done that now. have you got any suggestions on what I can do to fix this. The reason I am desperate is because greenfoot is what I am using for computer science in GCSE and that means I need to practise this also at home.
You could try downloading a slightly older version. Have you had greenfoot on your system prior to this? Do you have a java JRE (or JDK) downloaded (one of the two is required -- I cannot remember, which off hand)?
@danpost
I have java JDK
How would I find an older version
I mean has been working for the last two days but has suddenly decided to stop opening itself and any projects
Maybe you could try renaming the last project you had open -- then try opening greenfoot?
Its fine now I have found an older but more awkward version that does work
