Help! I have been logging on succesfully every day for the last few weeks, but today, my viewer simply crashes in the middle of the startup process, i.e. before it gets to the login screen. I have tried other viewers but they all behave in exactly the same way. I don't know if it is any help, but interestingly my Yahoo Messenger is bahaving the same! I have checked that I have the correct and most up-to-date drivers for all my hardware and have also checked that I have the latest versions of Java, Quicktime and Flash. Any help would be very much appreciated. Further information Thanks for all the advice guys. I have 8Gb of RAM and 1Tb free on my HDD, on a Windows 7 machine. My internet speed is 50Mbs (Cable) I checked my antiviris and that wasn't blocking anything and checked that all relevent programs were listed in my Firewall. The problem still exists. I restored my system to 2 days ago, and hey presto it worked! My worry now is that there will be an update and I will find the same thing happens again!
