We will change that version in filebase for R2B45 when sPlOrYgOn will be ready with it. For this moment I can recomendate, too, the version R2B43 or R2B44 (Huntkillaz's page or KaszpiR's page).
And I may attest - AMX 0.9.9 works with podbot mm with Vexd_UM (I've played with it also). The latest official AMX still has some bug (recognizing people when bot is kicked), but it will be fixed in the new AMX release.
Don't forget install all modules AMX (like Vexd_UM for example) in metamod's plugins.ini (I don't mean about AMX's plugins.ini now) - this one in metamod directory.
But first try to disable by commenting out by semicolon ";" at the begining of the lines with calls for all plugins in metadmod's plugins.ini - except podbot_mm.dll only. Try only metamod and podbot and tell us if it works for You.
