[Psyrin]

i dont know what happened exactly, but there is this sign that no matter what i do, continues to pop up. it reads exactly this "Run-time error '75': path/file access error" the only option is the 'X' button and the "okay" button, but even tho i click those, it keeps coming right back. if you can please help me i'd really appreciate it, an email or a reply will be great, and please keep in mind that i'm only fifteen and i suck when it comes to this stuff...
my computer is a windows XP , please please help, the sign is getting really annoying...
