Client Problem after upgrade

Hi,

We have an old 2003 server that we still have some stuff on and we were using UrBackup 1.4 to backup the machine. I wanted to upgrade the client on this machine to 1.4.11 and run the install, but once upgraded the server never connected back to the server.

I looked in the Debug log and there is the following error:
2017-07-14 08:58:54: WARNING: Upgrading…
2017-07-14 08:58:54: ERROR: Error preparing Query [SELECT tvalue FROM misc WHERE tkey=‘db_version’]: no such table: misc
2017-07-14 08:58:54: ERROR: Error preparing Query [DROP INDEX filehashes_idx]: no such index: filehashes_idx

Would this cause the machine not to connect to the server?

I was able to upgrade other machines that are not 2003 to 1.4.11. I have tried removing and reinstalling different versions but they all fail to connect.

Any suggestion appreciated as I am unable to backup at the moment.

I re-installed the client hundreds of times, but this time it just connected to the server. Not sure why or if anything has changed.
