Dropping session C

<p>So I have tried to drop a class I am taking from session C but URSA responds with "URSA is no longer able to process this type of enrollment transaction at this time."</p>

<p>What do I do? I thought you could drop summer classes prior to the last day of the session?</p>

<p>BTW it's not an impacted class.</p>

<p>Please help!</p>
