Since reformatting my HP Pavilion & reloading WinME I can no longer use any version of the acrobat reader. Each version I load gives me the same error. The program begins to load, then stops with an error:

Acrord32 has an unknown error....will now close. I tried pulling a pdf file from the web and got an additional error:

Could not find Acrobat External Window Handler. I've searched Adobe's site for clues have come up empty.

Any of you professional gurus have an idea?
I desperately need to get the reader operating again. I pull updated files daily for my business.

Thanks in advance.
