Doesn't run on Ubuntu 13.04

GDevelop general
#1

So today I’ve downloaded last version of GD for Ubuntu. When I start it, I get message:

[code]Unable to launch Game Develop, a unknown error happened! Here is the full error message:

/home/vlad/GameDevelop/StartGameDevelop.sh: 37: /home/vlad/GameDevelop/StartGameDevelop.sh: ./GDIDE: not found
[/code]
Both StartGameDevelop.sh and GDIDE are marked as executables. What am I doing wrong?

P.S. launching as root user doesn’t help

#2

Try to do this:

-Launch a terminal
-Go in the Game Develop folder ( type cd /home/vlad/GameDevelop/ )
-Type:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:.

( Do not forget the period at the end of the command line !! Make a copy paste to ensure that the command line is correct

then

./GDIDE
#3

Perhaps you should add this to StartGameDevelop.sh?

#4

StartGameDevelop.sh already do that.

#5

I meant export thing.

#6 
sudo apt-get install ia32-libs
