Version 1.45S Null Pointer Exception

[fzanella]

Hi Everyone,

For some reason when I try to open some of my oib files I get the Null Pointer Exception:

java.lang.NullPointerException

Weird enough, other files will open just fine. Anyone knows what I can do? I must confess that I know zero of Java programming so any effort to help me will be greatly appreciated.

Thanks!
