Multiple Instances with opening files

Hi All

Just wondering if anyone has any thoughts on how to stop opening multiple instances on my machine?

I have spoken to our suppliers of the package at Leamington Spa, UK, who say they cant help me - even though we have spent so much money on their program - what cheek !!

In any case, I am trying to avoid the 'A journal file could not be created ect....'

has anyone else had this issue and knows how to fix it?

Im running Win 7 on 64 with Solidworks 2011

Any Help would be great - its a shame about their after sales support..!

Cheers

Will
