Error code with Maple Story

I downloaded all MS files making none was missing as well as the new client. Somehow, when I open the client, the program would open normally (during the first seconds, you see a black screen), but right after it would shut down and show:

error code:-2147287038 (Unknown error 0x80030002)

Is there a problem with the files or is it my computer?

files. Redownload your client somewhere else with the name: MSSETUP V75
