I am using HRD v5.0 build 2893. When I open HRD Satellite Tracking a dialogue box tells me 'A crash has been detected by BugTrap'. (My computer did crash - the 'Blue Screen of Death' - but neither HRD nor HRD Satellite Tracking were running at the time). Clicking on the 'more' button tells me 'HRDSatTrack.exe caused ACCESS_VIOLATION in module "C:\Program Files\Amateur Radio\HF Software Suite\HRDSats001.dll" at 001B:0034162E'. Closing the dialogue box automatically closes the Satellite Tracking program. I do not wish to completely un-install HRD for fear of losing all of my settings but I have run the HRD installation program again in the hope of repairing the fault, but without success. I have been into the program and deleted three files - 'HRDSats001.dll', 'HRDSats.dll' and 'HRDSatTrack.exe'. I have replaced these three files from a pre-crash backup of HRD program files, but again without success, so I restored the three deleted files. Any suggestions for curing the fault, please?
