Run-time error '-2147417848 (80010108)':

Automation error The object invoked has disconnected from its clients. The issue I am having problem with and the solutions I tried.... 1)New installation of windows 2)New installation of excel as well as a different version of excel still 2007. Nothing worked so far.why do all this you may ask...simple the .xslm runs smoothly at my workplace... but not at my laptop where I did all these steps. Even when I removed all the code...still get the error...How:I inserted a userform and then a multipage...and on a page of that multipage a command button.when I run the userform and click on the command button not only I get the error...the userform doesn't close properly (stays running behind the editor).Not only that but I have 2 extra problems,excel freezes but unfreezes after I save the xlsm and when I close the excel it freezes completely.Workbook closes normaly but after when i go to close excel still freezes...what is wrong????
