Label not found error on desktop during battle

[isidfe]

Hey

I'm hoping there's a quick fix for this because it is really very annoying. During one of the very first battles (Orcs on the March Campaign) against an Orc Shaman on Debir, the following message pops up regularly on the desktop, stealing focus, but requiring an Alt-Tab.

Label not found: add_blog_shaman_trophy_spent_1

Abort, Retry, Ignore

Selecting Retry bring me back to the game with no apparent ill-effects, but this happens repeatedly and makes the game unplayable.

I am playing the Steam version of the game on Windows 7, x64, and previously played Armored Princess (on Steam) without encountering this error.

Hopefully someone can offer a solution, thanks in advance.
