Hi and welcome !
First, please give us details on your
Computer system
Software versions
Connection hardware
Internet Service Provider
and all the rest of the usual info...
And, what should be the first really curious question...
You have obviously been able to post here...
Are you using your machine for connecting to the internet and these forums or are you using another machine ?...
Meaning, are you completely 'off-the-air' or only having problems with the programs you have mentioned ?
Hang in there... You will get it sorted !
