Can't connect to home wifi network with WPA2 AES

My Lumina 920 phone won't connect to my home wifi network which uses WPA2 preshared key with AES encryption. It says cannot connect to wifi network. I even copied the WPA2 password from my router's setup screen to a text file and uploaded this file to
my Skydrive. I opened the file on my phone and copied and pasted the password into the password field in the Wifi settings. My phone still won't connect. On my desktop PC if I copy and paste this password from the same text file I have no trouble connecting
to my wifi network. HOW DO I GET WINDOWS PHONE 8 TO CONNECT?!
