Ok, so I downloaded the trial of RPG Maker VX Ace, but some parts are still in Japanese/Chinese.
If I buy the full version, will this be fixed?
(Also, what happened to the help part of the forums? I've been away from this site for awhile )

Which parts haven't been translated?

I have the 30 day trial from here and so far I haven't seen anything wrong.

Whenever you hover over say a text box or soemthing, its still untranslated, or the attributes or equipment names under terms, its still untranslated. Or in battle, certain parts of that are untranslated as well.

EDIT: Whoops accidental double post here XD
EDIT 2: I'm just gonna redownload and see what happens.

Unless you sought after the JP version, you should have the English trial. Did you have the JP version prior? In any case, you may need to go to Degica's website at RMWeb to find a solution for this.
