Taking my first steps -- trouble already

[ISNorden]

Trying to create a fangame from scratch using the latest Essentials as a base. (I'm running RMXP 1.05 under Windows 10, in XP/Service Pack 2 compatibility mode.) Even though I have changed ONLY the game title so far, I get an error dialogue box and an empty screen whenever I playtest --

---------------------------
Pokemon Lead Balloon
---------------------------
Exception: Errno::EACCES

Message: Permission denied - Data/move2anim.dat

Compiler:2706:in `save_data'

Compiler:2706:in `pbCompileAnimations'

Compiler:4133:in `pbCompileAllData'

Please let me know what's causing the problem and whether/how I can fix it. Thank you!

It might be because of permissions and user rights. You should try to run RMXP in Admin Mode or put it in a folder that you can access without rights. By the way why do you use the compatibility mode? In my case RMXP is running just fine on W10.

I already have RMXP set to run as an admin every time (since I own this PC). My default user account is also an admin, so it puzzles me that I'd have permission-related errors. Should I do a clean reinstall of RMXP in a folder outside C:\Programs (x86), just in case?
