Fixed a minor issue where Channel level Statistics tag "_MsgResent" value was erroneously incremented instead of the "_MsgSent" count in certain situations for read attempts following a read failure. This situation could cause the "_PercentReturn" value to be greater than 100% but did not affect the value of "_PercentValid".
