after ignoring many requests to upgrade to version 10, i finally downloaded and installed the upgrade. when running i get this:
i tried uninstalling and installing using a variety of combinations including installing as admin, running in admin, running under compatabiloity mode (winXP3). when i do the winxp3 mode, i do get the program coming up and sometimes can see the pdf file, but then get the error popping up anyways. i also stopped all virus protection. i also can not install older version now. in IE, for install of version 8 or 9, i get the get+ (something like this) error.
