Anyone else having the following problem with Sprint & Versamail?

1) You attempt to open an .xls attachment by tapping on its icon (it looks like a yellow sticky note in my case - not sure what's up with that)

2) Versamail pops a message saying "Unable to find a plugin...would you like to open as text instead"

3) You open as text and get garbage characters

For whatever reason, Sheet to Go does not handle the file, nor does "save to card" appear as an option in Versamail.
