[geraintw1uk]

hi all,

i have installed a few mods but i now have a lot of errors in the error log, could someone tell me if these are to do with a particular mod. all mods that i have installed have said ok with 1.1 rc2 which is the version i am running. please can anyone help with this... if i uninstall all mods would that put thinks right or would i have to reinstall the forum.
i have attatched 2 pics of some of the errors in the log.
