i sent the info as instructed, but clicking anything shows the same. i guess it si unusable and error is in the code itself. just wonder if i should wait for the next version, or if someone else has seen this and knows of a fix or steps to troubleshoot. i saw some forum posts indicating that this working for some so wonder.
