Georeferencing window won't open QGIS 2.4

I had the georeferencer window open in QGIS 2.4 while project was running, I accidentally closed the Qgs document with the georeferencing window open (worked absolutely fine till then). When I opened QGIS again and clicked the georeferencing plugin, the window doesn’t open.

I tried closing and opening the Qgs doc, deleting temp files, opening QGIS 2.2, restarting computer, but the problem persists. I don’t see any error logs in QGIS when I try to open the window.

Any help or possible error checklist is welcomed.

Update
I’ve tried a quick re-install of QGIS 2.4, still no luck. looks like a complete purge is needed.

Update 2
I created a new user on my computer, it already has QGIS installed, and the georeferencer plugin works fine.
