All problems: checkpoint to old and fork, are due to dynamic checkpointing off - I stopped  vps for BTB zero-client and redirected dns-lookup to some pool.

I synced my home client to longest chain and i suggest doing the same :
connect=btb.ltcoin.net, or at least addnode=btb.ltcoin.net

DNS first node search has been redirected to some pool ,soon dns will be updated to btb.ltcoin.net as it proves to be the fastest one.

I run dyn-checkpointing on my private PC now, until I get my hands on some VPS.
