Bug when trying to use publisher for the first time

Game Dev Tycoon bug
#1

I tried to use a publisher to publish my game for the first time and this popped up:
screencap of error message

Any advice?

Sorry for the troubles. This bug is already fixed with version 1.5.4.
Just restart your steam client to make sure you get the update.

Seems to have helped. Thanks a bunch!

I am also getting the error, but my game says it is version 1.5.4

#5

I concur, version 1.5.4 and error still exists

@David_Taylor, @Zahael: Could you take a screenshot please. I think it might be a slightly different problem.

Found another problem with publisher contracts and fixed it with version 1.5.5.
Sorry for the troubles
