I accidently altered my WeiDU.log - does it matter/can i refresh it? :D

I was playing with the WeiDU log, was going to save it elsewhere as a copy and overwrote it

Does this turn the bg world upside down in some way? /can i continue to install mods? - When i went to try cdtweaks again it looked liked it wasn't aware that is was previously installed.

Thank you
