Togainu no Chi game start issue

I hope I am posting this in the right thread? Anyway:
I have the Togainu no Chi game downloaded to my computer and everything runs fine. Well, I installed everything onto my EHD because my computer memory was too low to download it directly on to there. But I accidentally disconnected my EHD from the computer and had to re-mount the CCD file because it disappeared when the EHD got disconnected. But now whenever I try to open the game, nothing happens. If I try to open it, the only thing that shows up is that image of the guy but nothing else. If I go to the install it shows "Game Start" as well as "Uninstall" but whenever I click "Game Start" nothing happens. I really don't want to uninstall and reinstall again because I don't want to lose my save data so is there some other way to fix this issue?

Edit: I finally got it to start but only after attempting to open it up a billion times. And I don't know how to delete threads, sorry :x I guess I can still ask the question of how to get it work the first time in case this happens again? Or in case someone is having the same issue. Thank you. :)

I'm having the same issue! I don't know what to do ....
