Could you try the attached script (aptana.sh) and see if the message center/aptana start page now show?

Place it next to the AptanaStudio executable in the aptana folder.

Also, if it doesn work, please let me know what the error is if any and also do you have Eclipse installed?

This can now be fixed in Ubuntu 8.04 Hardy by doing:

$ sudo apt-get install firefox-2

This does NOT break an existing (default) Firefox 3.0 installation used for regular browsing.
