Sorry, had broke my elbow shortly after writing this, so was unable to reply till now. I did as you said and went to a different area, and took off everything I could that the space would allow anyway, and still got the error. One thing I did notice, is it seems to happen, when I use a different button (this HUD has 7 different ones with like the ability to put 20 ish animations in each.) So the first button works fine with the animations in it, the others after work as well, but throw the error message out.
Unfortunately, the HUD is not free, I got it from the MP for L$ 1. I didn't know if it would be okay to post the link to it, so I have not, but could if it's okay in this situation.
