Sorry, jp, I told you I wasn't good at all in internet matters, I wouldn't even know where to start to upload a screenshot...(do I look very dumb?)
As for the link i sent, the fonts were normal Latin characters, but different style (more like "courier news" than like "arial"

.
I said nothing about the "error" notification wwhen posting messages, because anyway I managed to send them (if I went back after receiving the "error" warning, I could see my message had entered) and I didn't want to bother you at that moment.
