I had successfully built an existing book (recompile actually), it had shown the bubble at the bottom for preparing, it had then started indexing. Then it crashed. Windows 7 x64.
7658.Verbum Log Files.zip
It should be interesting to see what Logos have to say about "The process cannot access the file 'C:\Users\AWALT\AppData\Local\Verbum\Data\salqh3bh.gwa\LibraryCatalog\catalog.met' because it is being used by another process." because the other process was the VerbumIndexer!
I will create a case about this issue.
I've been able to reproduce this crash locally; a fix should be in the final release of 5.2a.
This will be fixed in 5.2a Beta 3.
I have nothing else to add except to say THANK YOU! You guys really do fix things quickly over there! Thanks!
