Never had ANY issues opening attachments with Comcast Internet ... changing over to FIOS Internet has caused me no access to downloading ANY ATTACHMENTS. I, primarily, use my laptop for business and am at my wit's end at this point. Any attachments start out opening, then it states it can't be opened. My PC opens attachments which was changed over to FIOS at the same time but I need my laptop as I am always out on business. Please help as I'm not in the mood to speak to someone or go through 1,000 voice mails. Thank you and Happy New Year!
