I have been instructed to use the following in conjunction.
Trados Translator's Workbench v.184.108.40.2061 (build 441)
Trados MultiTerm v. 220.127.116.11
Are there any known compatilibity issues that I need to be aware of?
Both programs interoperate perfectly.
This combination s more stable and predictable than WB 6.5 and MT iX (aka MulitiTerm 6).
Of course, they're rather old now, so you'll be unable to work with some newer file formats (e.g. Office 2007, Open Office etc.).
