Error message in opening or cleaning a TagEditor file:
Failed to retrieve tag toolbar settings for plugin file format error
Open TagEditor with Jedit or note pad. Replace "InDesign Filter 184.108.40.206" for "Indesign Filter 220.127.116.11" (depending on the Trados version, the D might change from capitalized to lower case) or viceversa. If you change it when you opening the file, you have to make sure that you change it back before submitting the file or your client/PM won't be able to clean it.
