IBM Installation Manager: File Not Found Error on Update

For the past couple of days I've been trying to update my local copy of RTC on RHEL/Linux and have been hitting an error related to a file not found. Installation Manager can't seem to download the zip file below (and sure enough I don't see it on the server it's trying to get it from).

http://download.boulder.ibm.com/ibmdl/pub/software/rationalsdp/rtc/v2/client/2002-ifix1/repository/native/org.eclipse.equinox.p2.bootstrap.gtk.linux.x86_3.4.200.R342_v20090122-989JESTEbig-SVaL8UJHcYBr4A63-1259779188154.zip

Here's the actual error reported by Installation Manager

Error updating.
