The problem for me is that this doesn't work (!!!)

If I delete the old client, clear everything in %appdata% except for wallet.dat and then install the new client, the client will not start !
Only after I copy everything back into my %appdata% folder, I can start the client again.
And then I have the same problem again.

Also please give me the command for adding nodes. And what is the syntax ?
Do I just type the following in the debug log:

addnode ["173.236.43.58:39565","66.69.215.216:64946","5.9.158.79:47779","178.125.216.61:63731","107.170.207.147:8500","8.38.76.74:8500","121.185.195.12:8500","14.201.25.59:8500","70.114.143.108:8500","124.168.225.125:50023","59.55.230.181:59019","65.128.192.240:8500","98.250.252.199:8714","88.8.127.16:49448","192.99.144.139:59973","198.101.10.110:8500","75.143.69.254:8500","86.163.25.105:59196","85.243.107.186:51194","211.149.148.150:58600","82.66.239.16:50554","124.231.7.138:6415","178.15.70.226:4178","77.185.64.103:56833","82.127.140.248:63416","83.227.236.11:54676","118.186.153.220:56250","203.173.207.126:59262","64.58.8.35:55490","213.125.187.244:1193","89.99.191.4:6691"]

Or without the brackets ?

Cause if I add this, also nothing happens.

Please help me with this. It's really frustrating.

Thanks
