I have a Lookout 5.1 process that occasionally has problems loading. When loading it will go to the "Please Wait" message, and will hang there almost indefinitely. On occasion, the process will eventually load, but sometimes can take up to a couple hours to load. The process is not that large, although the Citadel DB is probably close to 8GB in size. The L4P file is only 761kb and the LKS file is 302kb. Neither file seems to load any better then the other.
