Thanks for the replies - I have only ever used the default setting when installing mirc so don't think it's scripts? And I did use mirc.com to d/l from.
Originally I believe I was using 6.something but not sure which version exactly
Have typed the command as requested and got the following:
Vista 7.17 7683908b23e2cfd3ed883d5daf3eacae ok 1 0 0
Thanks
