Still not working, but I can access the main page of PRO forum .. just the main page. I think the problem is my internet connection because when I connect my home WIFI with other devices, there is the same problem. :Nervous:

Thank you for your guidance and support. :Grin:

Finally I find this site : sorry.. I can't post links as I'm a new user BUT I don't know what are they talking about, there are language and code I have never seen before. I don't know what should I do. help me please.. :Frown:
