Logos 4.2a had a bug which could cause download progress to go past 100% (see here and here for examples). There were actually two bugs: 1) a bug that caused the download to fail, and 2) a bug in responding to that failure that caused the progress over 100%.
We've fixed bug #2, but were never able to reproduce bug #1.
4.3 Beta 3 contains additional logging to try to identify why bug #1 is happening, so that we can fix it. If you have logging enabled, and Logos 4 downloads resources (particularly if it's downloading brand-new resources), please post your Logos4Indexer.log file on this thread so we can examine it. (We're particularly interested if it contains the message "Resource patching failed" but we'll look at any logs you have, just to verify that everything is happening normally.)
Edit: There are five pre-pubs shipping this week. Downloading brand-new resources is one of the test cases we're particularly interested in investigating. If you've purchased any of these pre-pubs, please ensure logging is enabled, then post your Logos4Indexer.log file from the download (before you restart Logos 4 to add the new resources to your system). Thanks in advance!
