Avisynth 258 wont work

[Disturbance]

i had v257 installed and all was working fine, but i wanted to get 258 to use the new resizers and to make some new pluggins work

but, i uninstalled the 257 downloaded and installed the new 258, and now i cannot load any scripts or encode anymore.

Where i used to drag my scripts into virtual dub for inspecting, vd just auto closes itself, and megui now loads the script but errors on the first pass (after analysis pass) and in script preview u try to move from frame to frame megui crashes,

and none of my old scripts work now either,

anyone got any ideas?
