Hi Ghaz.
The working hours are warning only!
however I have sent you some stuff which may help with the controller?
1 of the lads may have to assist with the access codes, as the ones I have given you are unproven.
Good luck

Thanks guys for help,I'll be trying it tomorrow

Ghaz, did you sort it out?
