Hi installed win 8 sp on Samsung Slate as upgrade to win 7 Enterprise. Was running fine with mail app serving both company Exchange mail and google mail with both calendars updating. Company password changed and Exchange mail stopped syncing. Only way I could see to change password was to reinstall the app and reinstall. On reinstall the app has hung in pending and will not complete. Other apps have installed since. Computer will not refresh fails half way through. Does anyone have any ideas to either reinstall the pending app or reset the download so I can get it to work before I have to resort to a full Samsung recovery? Thanks.
