You are sure that your internet connection is alright?
Source and target language are set correctly?
Thank you for your effort mate but of course my internet connection was alright; how else could I start this topic?
Anyways, resetting the preferences did the job. I guess this is the sole solution for all the problems regarding Cafetran.
Google MT (along with other MT services, Mymemory included) suddenly stopped working. They only display a table with two columns showing "Source Language" and "Target Language".
What I should I do to solve this problem?
