Hello Idillic,
I do not think the problem you have reported is because you have installed FPSC X10, since I have both installed on my computer and work fine within their limitations.
I do not know what operating system (Vista x86-x64; Windows 7 x64 or x86-x64 platforms) you are working on, but the best thing to doing is once again uninstall the FPSC X9, restart your computer and install it again.
Next you should upgrade to version 1.18.017 not the release 1.19. XX because it is yet a bit unstable. Now it's time to run the program FPSCreatorCleaner.exe as administrator.
Following that, on the icon of the FPS X9 right-click, the mouse button and click on the run as administrator. Case the software works nice. It's done. Case it still does not work to properly try install or reinstall the directx 9c which you can find it on the link below.

Next step is reboot your computer and run the FPS X9 as administrator. If it works well, it's done, otherwise you should contact technical support of the TGC and asking for a solution.
I hope this information may help you.
Good luck!
