sorry but i have been expirementig with textures and schtuff so i need a copy of the media file cuz there are plenty of files that are jumbled togeter
Your best bet is to follow these steps:
1 - Rename the current install folder to another name (from 'c:\program files\Universe Sandbox' to 'c:\program files\Universe Sandbox Current') - You may get a message saying this will mess things up. As long as you follow these instructions, you won't.
2 - Download the setup file again from this website.
3 - Reinstall Universe Sandbox into the default folder.
4 - Rename the new install to another folder (from 'c:\program files\Universe Sandbox' to 'c:\program files\Universe Sandbox Fresh')
5 - Rename the 'current' version back to the original name. (from 'c:\program files\Universe Sandbox Current' to 'c:\program files\Universe Sandbox')
6 - You now have an original copy of the media folder here: 'c:\program files\Universe Sandbox Fresh'
