[Typo3] HELLLP... can't create ANY content

HELLLLLP....

I was trying to learn how to use the extention kickstarter and now when I
try to install the extention that I am working on I get the following
error:

2: SQL error: 'Unknown column 'lg_country_iso_2' in 'field list''
(tt_content:NEW4224d6fc3dea8)

Now I can't install ANY extentions or content. What table should
lg_country_iso_2 be in? How can I track it down?

TIA
