One common mistake people make is zipping the .gdb file directly. You need to put the .gdb file in a folder named "Database" and then zip that folder.
Regarding the indentation in the post, any text that you want to preserve indentation and spacing can be wrapped in code tags. Highlight the text and click on the # button. The result looks like this:
Code:
MyGameSystem2 overrides GameSystem
{
BaseSkillPointsPerLevel 1
LevelsBetweenSkillPointRaises 2
SkillPointRaise 1
StartingSkillPoints 1
AttributePointsPerLevel 10
}
