I got the 15.08 SDK and try to run any of the demo apps (like 'flight' or 'new_year'). Of course I'm running the stuff on a local web server but chrome, firefox and IE produce these kinds of errors:

All browsers:
B4W WARN: BIN version does not match to JSON version: 5.4, required: 5.5. Some compatibility issues can occur. Reexport scene to fix it.

chrome:
b4w.full.min.js?v=15.08:638 Uncaught RangeError: Invalid typed array length

IE:
SCRIPT5084: Invalid offset/length when creating typed array

Firefox:
RangeError: argument 1 accesses an index that is out of range

How can this occur? Shouldn't the demo apps just run out of the box?
