HELP! I can't get the "@" or any Punctuation Marks.

My OS is Windows Pro in Japanese. My keyboard is an English keyboard. I can find all of the punctuation marks using “Microsoft Word” but when I use Scrivener I can get any of the punctuation marks to show their rebellious faces. Any suggestions? I mean the "@’ mark shows up as a “2” the apostrophe mark shows up as a colon. Damn! Bam! Wham! This computer is about to go for a swim!

When you’re typing in Scrivener, what language and layout is set in the Windows language bar? Are you using the Microsoft IME for Japanese?
