Adobe neither recommends nor supports two Acrobat/Reader products on the same computer. Due to issues you are having and other issues that occur as well. I would recommend upgrading to Acrobat 9. If you are not ready to upgrade yet, you need to remove one program and re-install the other.
Adobe’s Security Advisory APSA09-03 begins:
A critical vulnerability exists in the current versions of Flash Player (v188.8.131.52 and v10.0.22.87) for Windows, Macintosh and Linux operating systems, and the authplay.dll component that ships with Adobe Reader and Acrobat v9.x for Windows, Macintosh and UNIX operating systems. This vulnerability (CVE-2009-1862) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being actively exploited in the wild via limited, targeted attacks against Adobe Reader v9 on Windows.
