I have discovered that between TopSpin 3.2 and TopSpin 3.5pl4 there are some "interesting" changes in the format of the solvent data base file that are to the best of my knowledge undocumented. I had problems with solvents that we had previously added, especially deuterated trifluoroacetic acid, which Bruker treats as though it would only be used with a fluorine lock. I did manage to get around the problems, but I think it would be useful if someone from Bruker could provide some definitive information about all the changes in the solvent data base. I could look up what I had to do if you are interested.

Hi John,
Thanks for bringing this up! I am recently having the exact same problem as well. It locks out most of the digital BSMS and to reset things back to normal I hard restart the BSMS/2 followed by "cf". For some reason it also prevents a soft BSMS shutdown from succeeding, gives the error the ELCB is unresponsive and it loses the heartbeat for the BSMS.
It also happens whenever I try to use new solvents that I create using edsolv or edlock...even when the new solvents are just copy/paste of existing generic solvents but renamed!
Are you using TopSpin 3.5 pl 5? I have not had this happen with TopSpin
3.0 or TopSpin 3.2 but when we upgraded it started happening with MeOH-d4. Maybe it's a firmware issue?
I would love to hear the responses you receive to this.
Sincerely,
Paul
