Spring RTS Engine

When I wanna watch some replays. No problem on most of them, but on few of them I have this strange message and the replay doens't start.

I use TasClient.exe included in install (.33), I tried the updated b55 from Satyric but no improvment...

Please post the bug report and upload the replay on mantis.

Are you using the correct version of the mod and engine for the replay?

i've had this sort of bug on so many replays, its usually each replay has a different net message error, but they all give the same error each time.
