If, when printing a letter through Uniform a message comes up that says  "Word was unable to read this document. It may be corrupt. Try one or more of the following:........"

please check that there are no characters/symbols such as : colon, & Ampersand, >,<, ?  in any of the fields in Uniform. Also please ensure that if there is a { in any coding, that they are { and not [.

Remove or correct any of these, save and re-try.
