Is there some problem in download page?
I have seen that the date of the files is 22-06-2008. It seems there is not last night dump. Is this like that?
I missed getting these, as our cron runs very early. Does anyone have a copy of alternateNamesModifications-2008-06-22.txt and modifications-2008-06-22.txt?
I am afraid the dump script deleted the previous dump when moving the dump from the staging area to the download directory. I have changed the script to keep a backup of the previous dump. This doesn't help you now but will help in case this happens again.
In any case I did a couple of updates directly on the database in the last months so it is anyhow advisable to grab and load a full dump.
