Its all Greek to me!
 

Why did my english version suddenly change to greek? How can I change back to English. denny

If you check all your options on the PEERanha menu bar then you should be able to find an option to change language. You might need to re-start the program for it to take effect. I am not familiar with this program but most multilingual programs will have such an option either under View menu or within the program preferences.
