Blockchain no longer working

I have been using the GUI wallet beta .10 for some time and it worked well on a local block chain I downloaded. Then about a week ago, the wallet stopped communicating with the chain. I downloaded the latest wallet, but no joy. So I erased the block chain (in ./bitmonero)and tried to reload it. After a partial reload, I tried the GUI wallet again, still no joy.

So I tried the remote site (node.moneroworld.com). Although that worked fine in the past, it no longer does. I can no longer connect to it.

The log of the initial download of the new blockchain was:

The daemon will start synchronizing with the network. This may take a long time to complete.

You can set the level of process detailization* through "set_log <level|categories>" command*, where is between 0 (no details) and 4 (very verbose), or custom category based levels (eg, *:WARNING)

Use the "help" command to see the list of available commands.

The relevant error log extracts from monero-wallet-gui seem to be:

What has gone wrong with Monero in the past week? How do I fix it?

Thank you.

(Please forgive the jumbled nature of the message copies. For some strange reason, even though they show correctly in edit mode, your system ignores all the carrage returns and concatenates them all together as a single paragraph when posting the result. I tried to manually insert additional CRs in an attempt to fix the problem, but that only double-spaced the text. Hope you get that problem fixed.)
