This can be caused by a faulty text_(lang).properties. Which language do you use? If it is English you might be hit by this as the property names in texts_en.properties are wrong. I attached a corrected version of this file, try it in case you use English... It WorksForMe (tm) and corrected the same error here....
Hello. I have run into this error message. After a lot of trial and error (including following several of the suggestions in this thread), the only way I could get the error message to stop appearing during an album build was to change my number of threads from 3 to 1 (under Tools ==> Preferences).
I'm assuming this slows down jalbum. But at least it generates the album successfully. Interestingly, I can run more than one jalbum session at a time in order to build several albums at once even though the number of threads is set to '1'.
For what it's worth, I am running the following:
Windows XP Professional (all service packs installed)
Thanks for the heads up here. I have been grappling this error for years, (since using multiple core systems duh!). My old way of getting around it was to restart the process when it gave the error using the "only process changes" mode. This meant many restarts to get through my 13,000 picture library but I really like the skin and didn't want to give it up. Coincidentally I run a quad core AMD Phenom II and 8 gigs of RAM!
At least I can now run it over night with some confidence!
