[Plugin: WordPress eCommerce – MarketPress] Store Settings Tabs Missing

Hello! This is a weird one. The only tabs in “Store Settings” that are visible to me are “General” and “Presentation”. Funny thing is though, if I put in, say:

http://halftone.tv/wp-admin/admin.php?page=marketpress&tab=shortcodes

The page is there, but I can’t access it from my dashboard because the link tab is missing (along with all the others except the two I mentioned previously).

Any ideas? I have tried uninstalling and reinstalling with the same results.

Marketpress Lite version 2.4.2.
