Please don't delete any .dll files. As far as I know, they are all part and parcel of a program.
I'm sure someone with far more knowledge and experience than I have will advise further but I'm sure it's best advice, certainly for now, not to delete any .dll file!
I think, in the first instance, I would uninstall, then re-install, this program then see if it solves the problem.
As I have mentioned, someone with better knowledge and experience, will be along and can advise further.
