Star Explorers was not starting up for an unfortunate player. However, he had the good sense to let me know about it. By getting a little bit of feedback and having him run an updated version of the game under the testing branch, we were able to zero in on the cause.
4.1A includes this slightly modified script that should mitigate the issue for any future players who may have encountered the problem.
The Problem in Detail
For anyone interested, the problem was caused by a script that looks at the available monitor resolutions on the host computer. For reasons I cannot remember, the script only allowed up to 29 different resolutions. This caused the script to get stuck in a loop when it was run on a computer with a higher number of possible resolutions. I have increased the number of possible resolutions to 300, so hopefully it will not happen again.
I will be having a closer look at that script though, since it should not have behaved that way to begin with. It would be best if it did not have any limit to the number of resolution ratios, to keep it future compatible.
Thanks to the Players
If you are someone who purchased the game, and were not able to start it, please consider trying it again now. I know a lot of people who encounter a crash like this, and I don't really blame them, will simply leave a negative review and get a refund.
But, I am grateful to all of you folks who brought the problems in this game to my attention. In this case, it was actually pretty easy to fix. Sometimes these things can be tougher and take more time and patience. In any case, this game would never have become what it is today without the help of players who give feedback. So I thank you all!
