2. When navigating from Actions to Options, no window opens and instead the following error is thrown:

EDIT: Ignore second one. it was a caching issue after all.

I'm able to open Options from the Actions menu fine but when I leveled up I got the following:

@Achewski do you have Ace3 addon installed?

It was a caching issue once I cleared the cache under SavedVariables I am now only getting the first one: Interface_Vanilla\FrameXML\Bindings.xml:34 Error loading Interface/AddOns/Talented/Libs/LibGratuity-3.0/LibGratuity-3.0.lua

Thanks a lot, now it works (also the level-up message is gone)

Hey, i've the same issue and get the following message after loading:

When leveling up, the following message appears:

The LibGratuity error has now been fixed. I don't have the time to devote to level up a character to see what that last error is about; it might be related to the new code that other chap kindly wrote for me. I'll have a look when I get time. Does it prevent you using the addon without a /script ReloadUI()?

When leveling up, the following message appears:

Fixed in new pull request #114
The translation table wasn't populated if Talented wasn't used before leveling.
