Why can't I finish installing yahoo messenger?

Alright, I'll start from the beginning. I had been running version 6 of yahoo messenger. My internet connection was recently disconnected (for about a month) and when I finally got reconnected (through the same ISP) My yahoo messenger would say that the operation had performed a runtime error. I restarted my computer multiple times thinking it might have been some fluke in the program. Well it continued to shut down everytime I signed in. So after getting tired of that, I decided it was time to delete version six and install the newest version. Well I downloaded the msgr8us.exe program and began to run it. The installation will make it to 4% and say "Download of file has been cancelled or interrupted. File not completely downloaded." Then it says "The file C:\Program Files\Yahoo!\Installs|ymsgr8us.exe could not be opened." Can anyone tell me what's going on? I've disabled all firewalls to troubleshoot the problem, but no dice. Please help!

You have to fulfil these requirements:

Minimum 64 M B RAM for Windows 98 and ME

Minimum 30 Mb disk space needed to install


Additional features such as Calling, Webcam, and Yahoo! Music, require:


Windows Media Player - 7 or higher or higher


Webcam - Messenger compatible


A microphone, sound card, and speakers or a headset


The only feature that may be in question is premium Yahoo! Voice services which states the system requirements for phoneout as being Windows 2000 / ME / XP. Something they haven't mentioned above is that Macromedia Flash Player which is still required, it's an Avatar requirement, Yahoo! Games requires Java to be enabled.........
