@Roshan123, I am quite sure it is not permanent. Your account will probably be back in order by Monday. That is, I would wait until the weekend is over before really getting concerned.
@Roshan123, the arrow is an image -- not text. You are using the wrong GreenfootImage constructor. Try:
GreenfootImage bg = getBackground();
GreenfootImage arrow = new GreenfootImage("arrow.gif");
bg.drawImage(arrow, 500, 500);
@PascalFischer
(1) close greenfoot app;
(2) open project folder in file directory;
(3) delete all STRIDE files;
(4) re-start greenfoot and open project
@Kostya, I know. A lot of scenarios run much slower or become laggy on the site. Also, this is an old (2013) scenario which was only updated to work on the site again. I was not improved upon.
@Roshan123, I am updating all my older stuff to work. May take a few upload attempts before working -- may not ever get some working again. This one now works.
