Currently, I'm working in Spanish into Arabic project. But when I open the first segment, it refuses and Workbench display " (50016) DOnt use; as list separator in style name. Change in Control Panel/Regional settings..".
Can anybody explain what is this and why it happens and how to fix it in order to translate the files.
This has been discussed on several occasions - have you tried the forum search (search for "list separator" in this forum)?
Searching for "list separator" in the Trados Knowledge Base will lead you to the KB Article 438, where the remedy is discussed.
