You don't have anything to appeal - or worry about.
At the end of a benefit year, the states are required to reevaluate your earnings to see if you qualify for a new claim year. If your earnings are insufficient, your application for a new claim year is denied, your old claim is automatically reopened and you continue on the EUC tier program. This is standard operating procedure. The letters sent out are confusing because they don't tell you the whole story.
However - KEEP CLAIMING. All should be well. It occurs to me, however, that we are almost to the end of October. Your old claim year should have been reopened a couple of weeks ago. However, if you stopped claiming, that could have halted the process and you will need to call the unemployment office to reopen the claim.
