This thread is around, and I know that CA and MrP do check this section of the forum... but they may not have an answer. I mean, if they don't know how to fix it, they don't want to come here and tell you something that'll get your hopes up, but I'm sure they're aware of it, and would love to fix it.
I mean, at this point, all I can recommend is an uninstall/reinstall, but that's not guaranteed to fix your issue, and I do not know if doing so will lose your save.
