Sorry for the delay, the Stardock headquarters is on holiday until the 8th.
I recommend looking over the Support FAQ.
If nothing there helps with your problem, then please specify your system's specifications.
Also the runlog.txt file might have relevant information, it is located in \Documents\My Games\Star Control. If you could upload it to a cloud service (DropBox, Google Drive, One Drive) and post a link here that would help.
Thank you for your patience and patronage.
