Hey. I got my lovely iMac a week ago, after years as a writer using a PC and exchanging Word files with editors/publishers. For the first week, no problem, people sent Word files, I used Entourage and just clicked open. No problem. Then, after a week, I could not open any files. I got a message that said""uses a file type that is blocked from opening in this version..." what is going on? I have tried saving with a different name, saving as a docx, nothing works. I cannot open these attachments. Please help!
