It is not clear to me what you mean by this statement.

I assume your last "it" refers to the open office file. But I cannot tell
whether the preceding "it" refers to the Open Office program, or to your Excel
2007 program. Nor can I tell what "doesn't accept it" means.
Program crash?
System freeze?
Error message? (If so, what is the message?)
Something else?
