Reinstatement / GPA/ PLEASE HELP!!!

<p>I made the biggest mistake by reporting a D to UCLA on the grade change site (that only lets you explain in less than 500 characters) why I got the low grade. It was a mistake that I contacted my professor about and it has now been resolved and my official grade is a C. I told UCLA I was in the process of having it petitioned but they revoked my admission and I have been freaking out.
I explained that I was worried about not meeting the coursework/provision requirements but on the letter I got saying my admission offer had been withdrawn it said it was due to not maintaining my gpa. I only had 2 classes this spring and I got an A in a 3 unit class and a C in a 4 unit class making my gpa for the semester 2.85. My cumulative gpa is still higher than 3.5.
The admissions officer told me to send a letter of appeal and final transcripts with the grade correction and the decision would be reviewed. Will the 2.85 gpa I got in the spring be a problem?? If anyone has ever been in a similar situation and can give me some good news I'd be so grateful. I'm freaking out!</p>
