Upgrading Drupal

I upgraded to the latest version of 4.5.0 with no errors from the upgrade script, but am now getting the following message at the beginning of each page. The second message in repeated 6 times.

user error: Unknown column 'n.sticky' in 'field list'
query: SELECT DISTINCT(n.nid), n.sticky, n.created FROM node n WHERE n.promote = 1 AND n.status = 1 AND '1' ORDER BY n.sticky DESC, n.created DESC LIMIT 0, 10 in c:\program files\apache group\apache\htdocs\includes\database.mysql.inc on line 125.

With the newly updated version 4.5, I have inherited the following difficulty: I use a border and image with the 'breadcrumb' links, to fit in with my modified pushbutton-based theme. In the new version of drupal, the xtemplate engine, or drupal, does not put a breadcrumb 'home' or anything on the major node pags, such as /book or /image etc.

With my theme this means I get a squashed box, formed by my border / image, on these pages. Can anyone suggest a workaround? It is obviously intentional that these primary node index pages don't have a breadcrumb trail - or is it?

hallo to everybody.
after migrating from 4.4 to 4.5 I got stuck into profile customization problems. In details, I’d like to re-integrate into user profiles fields already inherited from 4.4 settings (especially avatars, now pictures).
Do someone can provide to me some instructions please?

since upgrading taxonomy.module released with 4.51 or cvs (same), i cannot add vacab categories or terms:

Fatal error: Call to undefined function: check_query() in /my/path/to/drupal/modules/taxonomy.module on line 784

I was using 4.4 (I think) and recently upgraded to 4.5. I deleted all my files (except MySQL database) before upgrading. Most of the site looks OK. However, in my previous installation, nearly all the modules I installed were working. Unfortunately, with this upgrade, a lot of my modules seem to have gone bonkers including (but not limited to):

I've been searching this forum but I cannot seem to find anyone that has had a similar problem. I upgraded from 4.4.2 to 4.5 and followed the instructions. With a few little tweaks it all seemed to work pretty well, however I use the system for an internal company portal and many of the pages are defined types with the flexinode module. It seems that everywhere we've used that to upload a file, the file link is simply missing now.
