The log contains many connection related errors. You seem to be using a proxy list – is this intended? Some proxies can have unreliable connections, which will result in those errors. If you don't want to use a proxy list, you can disable it in Options > Preferences > Connections tab.
There are also other errors in the log, and I cannot say what exactly could cause those. The first thing you should try is update Java, because Java 6 is unsupported and FRD may not work correctly with it. Windows XP does not support Java 8, but FRD works fine with Java 7. You can download Java 7 here: [
