Sage 50 Account Period stuck on last month

SOLVED

So i came into the office today and started to do some sales invoices. Maybe after i posted three invoices i noticed that account period was still stuck on 20. It should of been 21 due to it being a new month. So i went to switch account period, clicked yes for post all. Screen went away like always to tell you that it worked. Noticed that the did post. The problem though, the account period still remained at 20. So a few questions really, I read around and found a couple forums stating i should try posting in batch, yet as the admin, My posting method button is grayed out and will not allow me to change it. Is there any more steps i have to take in order to change it? Currently stuck on real time. Second question. Is there another way to fix the account period? I have no idea why it would re-loop the month of august(period#20)and not just go over to September(period#21). Stumped really because I've only been using Sage 50 for 2 weeks. Side note: It messed up my sales report and sales rep reports dates also T-T...
