OK, please excuse me if my terminology is not correct but, I have have done too much upgrading in too little time! I installed 2 new computers running Win7HP (I was using XP) and I installed MC15 on both of them (I had been using MC11)!
So I am on a very steep learning (beating head against wall) curve!
Here's what I just did as a test(?):
1. Shutdown Media Server on my server PC.
2. Made a change (track#) on a file in MC15 on server PC.
3. Checked the file on hard drive and verified that the tag was indeed changed.
4. Restarted Media Server on server PC.
5. Went to the HTPC and started MC15. The same file in the loaded library was not changed as per (2) above.
6. "Connected to library" in MC15 on HTPC.
7. The file was then updated to the changed value (track#).
8. Went back to the server PC and closed MC15. Restarted MC15 and did not get the "database read-only" dialog.
9. Crossed my fingers that all is well now.
Does this make any sense?
