Why does a new investment transaction not locate a current security.

Question

Multiple investment transactions concerning two securities up until last week.
 Then this week, cannot create new transactions because Quicken cannot identify/locate the securities.
 They are still listed on my Quicken portfolio summary. They are still listed on my Quicken Edit Securities List. They are still listed on New York Stock Exchange. Older transactions still contain these two securities. Thank you.

Thank you.
 Attempt at Purchase Transaction - Security (IEMG) not listed nor does Quicken find the actual security.
 Screenshots of Recent Transaction List, Edit Securities List and Portfolio List all show IEMG with no issues and with updated prices.
