OK, thanks for the report, but I will need more information to be able to understand what's causing your error.
- Which version of InSimSniffer?
- Is the message a popup dialog box or the big unhandled exception dialog? (if the later please post the stacktrace)
- Are you connecting to a dedi server or a local client?
- Are you connecting to an empty host or to one with a race already in progress?
- Does this happen with the old version of LFS or just Z32?
