Master Merchant main window is gone
 

Got a major problem I have no idea how to resolve.

I was using the outdated addon "Shopping List", it was using the MM's main window to display history of purchases.
But the plugin broke the window. When I let it display the purchases, window dissapeared and I am unable to show it again.

The key "Show/hide main window" just releases cursor, like the window would be there, but totally invisible. The stats window works though, all plugin also works properly, reads all data, shows the prices, everything is good... beside this window. No LUA errors or something.

Ofc, I uninstalled the "Shopping list", I also tried to manually reinstall the core MM but it didn't help. I am afraid to loose my sales history.

Try this.
 

Go into your saved variables folder in your ESO documents folder.

Remove the LUA file called Master Merchant; but, keep the MM# data LUAs'.

This will fix any bugs with your main MM but keep your data.

Logout before doing this or the game will restore the savedvars file from internal data!

It helped. Thank you very much!
At last attempt I didn't logout, and it didn't work, but now after the logout everything went fine. :)
Thank you again!

D'oh
 

Whoops sorry forgot the logout bit.
