Hackshield Error 516

[Tesiqurasa]

I'm just going to say everything I did, I'm not sure what caused this.

I recently tried to dual log on this laptop, which I doubted would work (32 bit Vista Office).
The user account I created had Admin capabilities.
I copied my Nexon folder from my normal user to a flash drive, then again to my 2nd user.

I opened maple perfectly fine on my 2nd user. I switched users and tried to open maple again, but got Hackshield Error 516.

I logged off of maple on my 2nd user, and logged out of that user. I went back to my normal user and tried to open maple, but still got the error.

I restarted my computer, but still the error.

I deleted my Hackshield folder entirely, hoping it would re-instal itself like when hackshield was first implemented, but I still got the same error.

Currently, I am redownloading maple, so I don't know if that has worked. If anyone has other ideas, I would appreciate them.

You're using Windows Vista? I don't know much to be honest, but I do know that Vista can cause problems with running MapleStory. Could you play it on Vista without any problems before?

If you cant, you should just use XP, it's faster and more convenient.

I've got the laptop to run Vista effectively, so for everything non-maple, it is much better. I was an Architecture major last year, so I needed vista to run most of the new programs used.
Yea, I could run maple fine for the past year on this computer, and even dual-log a while back.

I did eventually fix it though. Just reinstalling didn't work. I copied my Nexon folder from my other computer to this one, so it works fine. Oddly, reinstalling didn't work, but this did.
