Since upgrading to CMS 7.5 SP1 HF4 - getting errors when imaging

I just upgraded our environment to CMS 7.5 SP1 HF4

Ever since I can't get the Deployment Package Server on the Site Servers to update from version 7.5.1599 to 7.5.3251 as per documentation

Also when imaging - both from an image and SOI with DA getting the error below:

ErrorMessage: Exception has occured in File SMPPackage.cpp at Line No 793. Type of exception is GeneralError. Error is Default Message Exception in CSMPPackageException. Error Description is utilCSMPPackagegetPackageRawWebPath. Value of Windows error code = 183 and message is Cannot eate a file when that file already exists.

Seems like we lost all DA drivers in the upgrade so I had to restore them from backup...

Not sure if the two issues are connected  - any ideas?
