Does the above description fit your problem?
Then, most likely, your problem is caused by your e-mail address not being confirmed.
Castellon Edit (for details):
More detailed explanation: When you register, and every time you change your e-mail address here, the forum will automatically send you an email (that you need to click a link in) to confirm that the e-mail address is legit and that you own it.
So if you missed one your account is restricted.
Castellon EDIT: Solution A) Try this first as it is easier. http://forum.paradoxplaza.com/forum/...o=requestemail
Solution B) - Try changing your registered e-mail address (you can change it back again immediately) and check your inbox (including the spam folder).
If you then change your e-mail to a nonsense one and then back to the one you want, the forum will send you a new confirmation email to the address you want to use. Act on that new confirmation email and you are done.
Hopefully this solves your problem. If not, please let us know.
