I installed the beta and observed on start the program seemed to be stuck syncing. I let it run for about for about a half hour and then pulled the Logos log (attached) to see what was happening under the hood.
Initial launch start was at 4:06:40
At 4:07:16 the program begins a cycle of rebuilding the Library Catalog Index and trying to replace it. This cycle continues to repeat throughout the remaining wait time indicated in the log.
I finally hit the start now button to force the program to start.
I know others have observed similar behavior in the install and startup of Beta 1
