Jim,
Did you not also get a CTREE error message while your Off-line Server
was up (something to the effect of "Omega Server could not open Target
File")? If so, chances are that you were inadvertently pasting in data
contained in a corrupted data file. This then corrupted your index file
(ISAM = Indexed Sequential Access Method). In general, CTREE errors
imply corrupted index files.
Here's what I did (that worked) under similar circumstances about a year
age (running TS 4.0):
1. Delete: 40BONN5.IDX; 40BONN5.DAT; 40BONN.IDX
2. Bring up Off-line Server
3. Exit Off-line Server
4. Bring up On-line Server
