hello man thanks for replying 

 ok I have no software conflicting with msn messenger 

 the only addon I had was msgplus and thats what im currently having an issue with I do have admin rights 

 and i am also right clicking and run as administrator on the setup file 

 the contact list issue is msn server side issue and they advised me to get a new hotmail address and to import my contacts over i have now done this 

 and all is fine i did however delete my cache and so on and to no prevail 

 so im not sure what is wrong is there possibly any registry keys which may have been left behind with msgplus that may be hindering me from reinstalling?
