Hi Everybody again !!
After trying different solutions for a while , I finally resolved my problem. My system is Ubuntu Studio 14.04 . I 've realized that the file stereo-tool.rc contained an invalid character ( probably after installed the new version of Stereo Tool over the old one ) . So I deleted the file ( 'cause ST reconstructs this file again when it loads for the first time ) and kill jackd and all other processes, open qjackctl again and start stereo-tool-gui-64 BETA 7.71 025 and it worked . Now I'm tired , but tomorrow I'll try delete this file again and install the 7.73 version -
Sorry for my first post , didn´t intend to bother anybody ; I think Hans is doing great work and I'm eternally grateful to him for this tool.
Bye and thanks again
