This occurred on SWx 2004 SP3.0 files located on a Netware 5.0 server. We had a power failure while SWx had this assembly open on a XP Workstation that did not crash the server, but the workstation did shut down. Ultimately the server had to hard booted to resolve start-up problems. When attempting to access the assembly, many parts in the assembly could not be accessed by the assembly file (unexpected error). Went back to the back-up tape for the previous day version, loaded that, same problem. Any ideas before I recreate the assembly?
