LUA Error on Startup

[marastu]

I have an error happening on initial login. I don't get this error every time, but I get it enough to be annoying:

Try doing a full guide wipe/reset.

1. exit WoW
2. go to the WoW/Interface/Addons folder and delete the ZygorGuidesViewer folder
3. go to the WoW/WTF/Account/<accountname>/SavedVariables folder and delete the Zygor files in there
4. run the desktop client and install a fresh copy of the guides
5. go back in game to test and let me know if that fixed it

It prompted me for an item upgrade this time instead of erroring out, so it may be resolved. I'll report back if it crops back up.
