there's 2 possible fixes for your error but first try restarting the launcher, making sure the icon has gone form the task tray and from task manager before restarting
then if you still have the same problem browse to your lotro install folder which defaults to c:\program files\turbine\the lord of the rings online\
program files(x86) on 64bit windows
find the 4 folders patches, forward, bindat and raw. if any of the folders contain anything delete the contents
note: some of the folders may already be empty
restart lotro
update: I tried the solution above, NOT all the groups were found, but there were a lot of vignettes updated. the launcher started but hung at the same point.. /sigh
