Okay, I see.
First of all, are you running a Windows system or a Mac system? Because originally you posted in "Mac installation" topic.
1) I've been told OR() trigger exists in IWD(indeed, on installs with official expansion(s) it works fine, but without HoW/TotL I haven't seen it). Can anyone with necessary knowledge please confirm/reassure me either way?
2) I'd like to correct this error as soon as possible(tonight, if I can), but in my installation DVALESTI file is "correct".
Will you please do this for me: copy your Setup-IWD.exe to Weidu.exe and run this command in your IWD directory:
weidu dvalesti.dlg
You'll receive dvalesti.d - please, e-mail it to me to kulyok, at yandex.ru, or attach to your next post.
With this information, I'll try to solve the problem as soon as I can.
