i have submitted the exercise and you did not tell me to make any corections however it has not been graded

I am having a very annoying problem where everytime i save my file and come back an error message pops up before opening my file and then torque is missing and i cannot figure out why i try linking him again and that doesnt work either. also how am i supposed to get the keyframes from the head the same as the antenna? Keep having a problem with that am i supposed to link the whole antenna while doing the keyframes for the head?

When I add the key frames for the antenna it will just move the keyframe added to the very last position. For example if I add a keyframe at frame 10 and then add one at frame 20 the one from frame 10 disappears and it just leaves that solid yellow line.

Sorry for the confusing wording. Here's some screenshots to help. These are for the last two keyframes at 29 and 39, but I tried to add one more at frame 19 and it just moved the keyframe to the last one added after each added keyframe. This feels terribly worded, sorry again.

It's not a big deal but just wondering what I'm doing differently.

This is kind of a meta question I guess but when I move the torque character the root or the 'empty' axis object remains at 0,0,0. Is this normal operating procedure? Do people normally hide this empty object once they start moving the character around?

I included a screen shot just for some clarity.
