Optim has been processing my file for a while, what is going on?

If your file is a very large file, processing can take a few minutes. If it appears that processing has not progressed within 5-15 minutes, then some issue must have occurred. If this happens, then we advise you to submit a support ticket so we can look into and quickly fix what is causing the issue.
