Cannot log in to my android phone anymore

Cannot log in to my android phone anymore

Few days ago I got firmware update in my S3. After update, I realized the
default QWERTY keyboard is lost. There was only voice input. Then, I
downloaded painfully "Go Keyboard" with voice search in android market
then everything was fine.
Today, I had to encrypt my phone because I wanted to use my company's
Google app service in my phone as well. I encrypted phone with password
given. When phone re-started and asked me password, there is no keyboard
to type in. Go Keyboard probably doesn't appear before decrypting phone
because it is an installed app.
Now I have many, files, pictures which are not in cloud. What should I do
in this case. Can't I enter password from my PC someway.
Please help me if you can.
