Addon: Missing Trade Skill List Error Message.

[Gearslinger]

When I hit the "G" key in World of Warcraft The Burning Crusade Classic (WOW TBC) I get an error message that reads:

"Missing TradeSkillsList_TBC has been blocked from an action only available to the Blizzard UI. You can disable this addon and reload the UI." Then it offers 2 buttons to press: [Disable] or [Ignore]

Why am I getting this error message? I am running the latest version (v2.5.08) of the addon for WOW TBC.
I have even tried to reinstall the addon. I still get the error message.
I did use the CurseForge app to install the addon originally and recently (like 10min ago) to reinstall the addon.

If I hit the "ignore" button it won't show up again until I either switch toons or just log out and back in. It does not matter which toon I play.

Does this addon need an update or do I need to fix something on the computer?
I have a lot of other addons, are there any known issues with other addons?

I have been getting this same error for some time now and it only happens when I open up the Social window and select the Guild tab. The error almost always pops up a few seconds later, but, as noted above, if I click the Ignore button then I don't get the error until the next time I log into the game.

Missing TradeSkills List (TBC) v2.5.08

This is still an issue as of this point of time.
