Have you updated tmodloader since the version of tmod itself has changed.
I'm running 0.8.1.2
thats the newest i've found.
I also tried the manual download from the listings page by tmodloader an manually placing it in my mods folder... still it shows 0.92
in modbrowser i see it under "updates" and as soon as i update it, reload the list, it'll be available for update again... super strange :/
