Repeating BEAST 1.8.4 returns a parsing error

[lingo]

hello,

Having made some changes in the nexus file only, I tried to repeat the run of an old xml file.

However, in spite of no other changes I now get a not understandable

"Error parsing '<alsTreeLikelihood>' element with id, 'bdLikelihood':
No rescaling scheme is currently support by the mutation-death model bdLikelihood"

It cannot be the actual Java version?

Any idea?
