"This translation memory will not be used..." etc. - why??

Question

Hi all, 
 When translating certain projects I get this error message when I try to add my own TM: 
 Swedish (Sweden). To edit the translation memories used for these language pairs, go to the individual language pair level.' with an OK button." /> 
 On the one hand, I'm wondering if this is blocked by the client (as I don't have this problem with all projects) but on the other hand I can't see the sense in sending me a Studio file if I'm not supposed to use Studio functionality? Or is it something completely different I'm doing wrong? The termbase set by me IS working, however. 
 FYI, the client hasn't attached its own TM to this project AND I've tried with both UK and US English but get the same error message. 
 Thank you in advance for your input, 
 Alessandra

Hi Alessandra Cazzola 
 
The reason you are seeing this is because the project you have received was set up with the TMs at the language pair level. You have tried to add your TM at "All Language" pairs. All you have to do is add your TM under the specific language pair level where you will probably find the project TMs from your client as well.
