Software Glitch


I am seeking an answer to a software problem I am having concerning my web software.  This problem has just started and is causing a problem.  Every time I upload to my website, the page will upload fine and then as soon as it does I get a ding and then my entire system freezes up and I have to reboot.  I am running Microsoft Expression 4 on Windows 7 Home Premium 64 Bit Service Pack 1.  If anyone can give me any help I would appreciate it.  Everything else works fine on my computer and there are no problems except for the problem with the web software.  Sometimes I also get a dialogue box which states "Ready to Process 200" and then I am unable to even upload.  I have to close the program and then re-open it.  If anyone has any suggestions, please help.  I can be contacted through my e-mail below.

Thank you
