Help - following the instructions, I went to the asus website to download to my pc the necessary files to sync my calendar and address book with my tablet. However, after download, (Windows 7, 64 bit) I find that the files can not be opened as they are .rar files. Has anyone else encountered this problem and how do you get around it without buying access to a program to "unzip" the file? What I am doing wrong? It's very frustrating not to have access to my address book.
