[SOLVED] AVRDude Not supporting Mega2560 (Eclipse Arduino Plugin)

Could someone familiar with using AVRDude from Eclipse please post the details from their programmer specifications page for the Mega2560? I am not using the plugin, but I do have Eclipse working for the Uno...I just cannot seem to get it to upload for the Mega. I got the settings from the boards.txt file, but even with those the upload fails. There is indeed an error window that pops up for about 100ms, but it's gone way too fast to get any idea what the issue is. Then when I try to go back into the project's preferences to edit the programmer preferences, I get a message to the effect of

The currently displayed page contains invalid values.

This generally appears when I select the AVR > AVRDude menu option there in the lefthand page. However there's really no indication as to which values(s) is(are) invalid...

So if someone could share the settings they've gotten to work with AVRDude and the Mega2560, I would greatly appreciate it.

Thanks in advance.
