missing adobe reader icon and error code 2

Adobe reader icon disappeared. The text is still in place and space for the icon is still listed but no icon. When I click on where the icon should be it starts to open then disappears. Top left corner of playbook flashes and shows an error " unable to start application adobe reader - Error code:2 " I rebooted my playbook still no go. Tried to uninstall adobe and it just spins, after 30min nothing happened. Rebooted again and tried to install via app world but its shown as installed and only gives the option to delete.(which it won't do) checked application permissions and its set to allow. Any ideas how to fix this short of doing a wipe and start clean?
