CMS related database error

[karma010]

Ok, so like a fool, I attempted to uninstall the CMS via Plugin Manager. It then gave me this error while attempting to uninstall it:

Database error in vBulletin 4.2.0:

Invalid SQL:

			DELETE cms_widgettype, cms_widget, cms_widgetconfig
			FROM package AS package
			LEFT JOIN cms_widgettype AS cms_widgettype
				ON cms_widgettype.packageid = package.packageid
			LEFT JOIN cms_widget AS cms_widget
				ON cms_widget.widgettypeid = cms_widgettype.widgettypeid
			LEFT JOIN cms_widgetconfig AS cms_widgetconfig
				ON cms_widgetconfig.widgetid = cms_widget.widgetid
			WHERE package.productid = 'vbcms';

MySQL Error   : Table 'xxxx.cms_widgettype' doesn't exist
Error Number  : 1146

Now whenever I try to uninstall any other plugins, I get that same database error and the plguin fails to uninstall. I tried running the upgrade script, but get another database error on step 31:

So apparently when I attempted the CMS uninstall, it removed the database tables, but didn't complete the process? After some searching (which I should have done to begin with) I now realize that I should have just disabled the CMS, not uninstalled.

My question now is: How do I rectify this while still keeping my forum intact? As it is now, I can't uninstall any plugins...it just gives me the 1st database error I posted. Like I said, I tried the upgrade script, but that gives me an error, I tried manually adding the tables, still get errors, I tried reinstalling CMS using the XML file via Plugin Manager...another error.

Any help would be greatly appreciated!
