Hello I have two problems with the version of ubuntu 1.9.0, when I go to save the work it does not give the option to save it in Zip, it only gives the option to save it .ctb, I do not know if it is my thing or some bug. As I could not save in zip with version 1.9.0, I reopened version 1.8.1, but when it is executed, it loads everything, the program closes without previous error, I think that are the machine profiles that the new version has more parameters that the old one does not have, Could you tell me where these profiles are saved to delete them and thus be able to open the old version? Thanks
