Cannot restore plm error: Could not read config file

Hi All, Recently we've been having some issues with our motion sensors not working (any of them) and some other intermittent issues. In the past to resolve this we've restored the modem (plm). But when I try to do that now, it gets to about 7% and then fails with an error message: Could not read config file [./FILES/CONF/50B976.REC]. The device that seems to be an issue (50.B9.76) is a Dual Band SwitchLinc On/Off switch (2477S) and it seems to be working fine, although if I try to restore that device I get the same error.

Any suggestions on how to resolve this?

Is this with an eisy, it sounds like an isy problem?

It looks be the sd card if going bad. You can remove it and try running an eraser over the contacts and cleaning with alcohol.

If you search the forums for SD card you should find more detailed info. Also it may be time to replace the SD card

I disabled the switch and then I was able to restore the PLM. Still not sure what's going on with that switch.
