The last version of Balloon3D-All is from 2004. I think you should load 
Balloon3D-1.1.2.mcm.

The cause of the error is that Character >> #digitValue now returns -1 for 
all byte characters (asciiValue < 256) that doesn't have valid #digitValue. 
This was different earlier. The number was negative, but not always -1. 
According to the comment the only requirement is to return a negative 
number.
There's another case when you'll get an error. The characters between $a 
and $z now also have valid #digitValues, but the VRMLStream class >> 
#initialize doesn't expect that.
