Tried searching for fresh hosts? ie: re-search each file that's slow. Generally, this has always worked for me for years. And 5 mins or more later using the Get More Results option.

Sounds like your software firewall or router is firewalling your LPE in part. Might need to add fresh exception for LPE. One way is go to your control panel, open up the firewall from there & use the Add option from the Exceptions tab window. I presume you are only using one software firewall & not two. Two software firewalls can cause issues, & may actually result in less security & not more due to their clashes. And may cause issues for LW.
