Failed to obtain a trial serial number from N Titles server., yes, because it happens to us all.. Options

So, to skip to the main point, something came up that made me have to re-install RMXP. Well, when it finished installing, I got the infamous "Failed to obtain a trial serial number from N Titles server." no problem I thought, this has happened before when I've re-installed, I just set the compatibility to windows XP, and run in admin mode. Well, that didn't fix it.

here's what I have:

Windows vista Ultimate (urgh)
RPG Maker XP (still have installation package)
RPG Maker XP serial key (I spent $60+ on this, and am not about to give up on it.)
Uniblue RegistryBooster2


And here's the methods I've tried already:

Compatibility/admin mode
Re-installing/restarting (even to a different directory)
Taking ownership of RPGXP.exe and PSIKey.dll (also setting full control, and taking ownership of the Enterbrain folder, and restarting after doing so to both.)
RMXP registry keys (the keys that fake XP into thinking your trial is up so that you have to activate; also tried restarting after.)
Cleaning up the registry (one'd think that after fixing 407 errors that the problem would disappear..)

(I've tried all of these with/without internet connection, and with firewall on/off. Restarting frequently)
No my version isn't pirated (I downloaded it from one of the RMXP site's mirrors, download.net I think.), no it's not illegal, yes I bought it, yes I used my own money, yes I still have my serial key from when I bought it.

So if anyone knows of a way to fix this problem without doing what I've done (or by doing it differently), could you tell me how?
