[Opensim-users] Error with script

[Katronix Serf]

Hi all,

I think my web provider re did some stuff on my vps, I'm trying to get 
everything back working like it should be but now when I try to run 
scripts I get the error in the code edit window:

(0,0): Error CS0040: Unexpected debug information initialization error 
`The assembly for default symbol writer cannot be loaded'

Can anyone suggest what I may need to install to fix this?

thanks,

kat
