LDAP Query: Update causes "Fatal Error" after running update script

My setup: Drupal 7.18 / IIS 7.5 / SQL Server 2008

My issue: This issue is confusing so I hope that I can keep convey what's occurring on my end:

I just attempted an update from LDAP 7.x-1.0-beta12 (Aug 20, 2012) to 7.x-2.0-beta3 (Dec 7, 2012). Copying over the files worked fine, but then I received an error after running the update script with these updates:

1ST ATTEMPT:

These updates showed up on the list:

ldap_authorization module

7201 - moving some groups related fields into ldap server module
7202 - remove user ldap authorizations field. its in $user->data now
7203 - make all schema field names lowercase in ldap server to deal with cronic case sensitivity issues

ldap_query module

7102 - make ldap_query.scope field small int instead of tiny int for ctools bug

Error that I received on the 1st attempt:

Fatal error: Call to undefined function ldap_servers_module_load_include() in E:\inetpub\wwwroot\drupal\sites\all\modules\ldap\ldap_query\ldap_query.module on line 116

2ND ATTEMPT:

These updates showed up on the list:

ldap_authorization module

    7201 - moving some groups related fields into ldap server module
    7202 - remove user ldap authorizations field. its in $user->data now
    7203 - make all schema field names lowercase in ldap server to deal with cronic case sensitivity issues

ldap_query module

    7102 - make ldap_query.scope field small int instead of tiny int for ctools bug

ldap_servers module

    7106 - add account_name_attr field to ldap_servers table
    7107 - remove allow_conflicting_drupal_accts from ldap_servers table
    7108 - add group related fields to ldap_servers table
    7109 - adjust group related fields to ldap_servers table
    7110 - adjust group related fields to ldap_servers table
    7111 - add field groupTestGroupDnWriteable to ldap_servers table
    7112 - add field testingDrupalUserDn to ldap_servers table
    7201 - upgrade as much as feasible for 7.1 to 7.2 branch
    7202 - make ldap_servers.bind_method field small int instead of tiny int for ctools bug
    7203 - make all schema field names lowercase in ldap server to deal with cronic case sensitivity issues

Error that I received on the 2nd attempt:

Fatal error: Call to undefined function ldap_server_module_load_include() in E:\inetpub\wwwroot\drupal\sites\all\modules\ldap\ldap_authentication\ldap_authentication.module on line 79

Also, the following notices/warnings appear on LDAP Help page:

Notice: unserialize(): Error at offset 0 of 867 bytes in LdapAuthorizationConsumerConf->loadFromDb() (line 98 of E:\inetpub\wwwroot\drupal\sites\all\modules\ldap\ldap_authorization\LdapAuthorizationConsumerConf.class.php).
Notice: unserialize(): Error at offset 0 of 867 bytes in LdapAuthorizationConsumerConf->loadFromDb() (line 98 of E:\inetpub\wwwroot\drupal\sites\all\modules\ldap\ldap_authorization\LdapAuthorizationConsumerConf.class.php).
Warning: Invalid argument supplied for foreach() in LdapAuthorizationConsumerConfAdmin->mappingsToPipeList() (line 532 of E:\inetpub\wwwroot\drupal\sites\all\modules\ldap\ldap_authorization\LdapAuthorizationConsumerConfAdmin.class.php).

And clicking on the "Authentication" and "Profile Mapping" tabs each go to blank pages.

So I'm now reverting back to LDAP 7.x-1.0-beta12. Has anyone else run into this issue?
