After a quick check on the wiki in question it appears that editing is restricted to Autoconfirmed users at the minimum. Looking at the age of your account, created today, I can say without a doubt that you do not yet have this permission on your account. According to this help page you need to wait at least 4 days from the date of account creation in order to have this right automatically added to your account.

In 4 days you will be able to edit pages on the requested wiki.
