plz tell me how can i solve this problem >?
I have already gone though this link
i am not getting ezpublish 4.4 version
If you had run the scripts in the upgrade documentation, then you would not have gotten error referring to created pre-existing tables. Due to the unknown differences between the 4.3, 4.4 and 4.5, it is recommended to do incremental upgrades from 4.3 to 4.5 to guarantee that all necessary changes have been made.
Since I am not a paying customer for this software like yourself, I can only recommend actions based upon the information given. Your current list of changes appears to have differed from their recommend actions. Hopefully with the purchase of the software license you have included support, I recommend contacting the company through their inquiry submission form at http://ez.no/Requests/Contact-Us to request their assistance with your problem, they should be able to patiently walk you through the necessary modifications.
