A question about options related to a stock split.

Yesterday WKSP underwent a 1 for 10 reverse split. I have a $3.00 option call expiring Friday. Because of the split the stock went from $0.35 to $3.50. The option has changed symbols and it seems there is no interest in buying. Furthermore you can't acquire any more positions. Have you seen this before? Is my option contract worthless now?
