HAHAHA i just wrote you an email about this update Edge
Renters what i did is this:
Even though you can't overwrite the metamod, adminmod and hlg dll's and some other files you can rename them.
So i just renamed admin_mm.dll to admin25050_mm.dll and then pasted in the new admin_mm.dll (oh ya don't for get to double check your plugins.ini for spelling and restart your server so that the change takes effect) as you can see edge i have found a way around it
I had to do this for hlg, adminmodm, and metamod because i prefer to do as much as possible before i start emailing edge like crazy with all the error i have created. But you also learn that way
