I cannot open attachments from my work email. When I try to open Word documents with ThinkFree, the documents just have symbols on it. So I dowloaded Documents 2 Go (which I used with my Treo). When I open with that, it says "It cannot be opened because it appears to be a plain text file". And the PDF file, with ThinkFree, said Error opening file. It may not be valid PDF file. (But it is a normal Adobe file we use all the time at work). What am I doing wrong??
