Can not connect with Mysql

I installed SC and test to create a Mysql local (windows), it worked,
After that I tested some examples app (with other kind DB), from then I can nit connet to any MYSQL neither create a new app with Mysql,

The error is "SQL STATE [2002], saying that my PC refused the conexion,

I uninstalled SC and intalled again (twicw) but problem keeps
Note the rest of DB works fine (APARENTLY)

Any help is very apreciate, I liked the tool but this kind of unexpected problems is so frustating
