Having started work on my railway after 5 years of non use, I discovered that I could not use the remote control function. I can operate trains tethered by a wire but not on R/C. I decided that a firmware update may be required so downloaded the latest version. Unfortunately Adobe reader wont let me open it, any ideas ? The central station display no longer works so that may make it difficult for me to carry out an update anyway. Would it therefore be a good idea to send the unit to Massoth for a new display and a firmware update ? if so how do I go about that. Thanks
