Compile Errors When login into HB

Hi Everyone

i get these errors since updating HB, i've tried a fresh install but still the same errors.

These show up when i log on and are preventing my bot from defending itself in combat

Anyone have a solution?

Honorbuddy is up-to-date

 

reinstall hb from scratch

also make sure you don't use it while it's still in the zip file

 

Already tried that

 

Glad i found this thread. I also am having the exact same problem he has described. It cannot compile anything. Ive fresh installed multiple times, as well as uninstalled my virus scan. On windows 7 pro x64. It was running perfect for the past month, i never changed a thing then 2 days ago it stopped and cannot seem to fix it. My log is exactly the same as his, everything fails to compile.
