Ok im sure this is a age old question but for the life of me i cant figure it out, i redid alot of things on my laptop and when it all started up again my XP said that i faild to obtain a trial serial #, ive been having to use my other laptop for work but i need to fix this so whats the best way?
Ive tried deleting it and redownloading it, I dont care if i have to buy it again but it wont even let me do that.

Have you resolved this,If not go to the new rpg maker official site and contact consumer report or sales support
*they have changed sites witch distributed the keys you need a new one, sales support will assist you*

>.> im currently going through the same thing

I just deleted all xp stuff off my computer and then redownloaded it and am using the trial for my projects. it sucks but oh well.

Have tried 'run as administrator'? cause i have the same problem as you, then my friend told me to try 'run as admin' and it work

I did and it got it back to where it said buy it or do trial, which is better then just closeing it out when i open it so in a way that worked.

....i don't see how it worked other then opening it,>.> im about to just repurchase it the rpg maker site has taken almost 3 days with no responses from there first email stating they needed my old product key/codes...i refuse to use the trial period for something i paid for
but i guess its worst to re-buy something i should have.

D: i don't have the patience for this.
