We purchased and installed the greenhopper plugin, and either due to have some remnants of an old demo version installed, or due to having manually create a 'Story' issue type, our greenhopper install did not perform all its setup steps, and did not receate the Story/Epic/Subtask issue types. From reading around, it looks like creating these manually won't do much in terms of GH 'knowing' about them.
Is there any way we can reinstall GH or have it recreate the various bits of static data it needs without losing the rest of JIRA data? I'm happy even with unofficial DB modifications if needed, just need to get this thing running somehow.
