I too was confused when the program started after selecting the "Refresh" option. It really confused. It seems that I will either have to get a new HDD to run the TD exclusively under its own OS, or format this one (but this isn't really possible). I tried the TD out on my laptop, work's laptop and also the other family computer, and it worked perfectly on all of them - except this one!
I thought that your option sounded viable, and tried running TD with my Firewall and Anti-Virus software disabled, but again images and dialogues were corrupt. I then tried reinstalling and re-installing IE6, but again nothing become of it! I was also going to update from SP2 (I never did this), but this isn't an option either, as I have a 64-bit processor, and there are known problems with this architecture. So it looks like my only option is to head over to the PC Store and get another HDD, install Windows and then run all Poker related activities from there!
Thanks for your help Corey, and if I can find a solution, I will let everyone know. I wonder whether or not it would be worth contacting Microsoft, and asking them whether or not they have any methods for either testing the ms-its protocol, or perhaps more importantly repairing it.
Thanks again,
Ben
