The "LOAD" message in the Front Display is set by the special aXeL extension. If the display does not change to "RUN" then there is a problem with the way the normal firmware has been extended to accommodate aXeL. You will need to re-flash your firmware using the failsafe mechanism. The easiest (and safest) way to apply aXeL is to use HDFW (and forget all about faffing with "extending" firmwares).
