Internet Explorer 8

Hello friends - I hope someone can help me with the problem that I'm having. While playing at Pogo.com I started having the problem of "hanging". So, I emailed them and asked them what I could do to fix the problem and they wrote back and told me to use Firefox to play their games instead of IE8. I then proceeded to uninstall IE8 after installing the latest version of Firefox using the Add/Remove button in the Control Panel. The uninstall got just so far and an error message popped up telling me "setup cannot copy the file hmmapi.dll.mui Ensure that the location specified below is correct or change it and insert "Windows NT Service Pack Uninstall Directory" in the drive you specify (C:\Windows\IE8) Now I have no IE and cannot delete IE8 nor can I reinstall it. I did a System Restore and that didn't work either. I do not know what else to do. If someone has a solution I sure could use the help. Thank you so much! Beverly
