Hi George
TEXTREAD is trying to import numeric data but encountering text fields which cannot be converted. Basically, your file contains the text "Desktop" where textread is expecting a number.
Also, to quote the doc "Note: textread is not recommended. Use textscan instead." Which might be what you need to do, but I can't really say.
You may want to re-post a question that includes:
  • What you're trying to do
  • A sample of the file you're trying to read
  • The code for what you've tried so far
