Hi, my company has recently shifted all our files over to dropbox. Now whenever I try to access a file via my comp, I get the error message "Excel cannot open the file because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension mateches the format of the file". This error appears for word documents and PDF documents as well. Essentially, I am unable to access anything on dropbox. However, if I use dropbox's browser, I am able to access the same files. Would appreciate any suggestions. Thanks.
