Check your squelch settings. On that scanner, the squelch is a separate ring under the volume knob. Sometimes, when turning on & setting the volume, the squelch can be inadvertently set too high because it is being moved along with the volume. That was a common glitch with my PSR-500, which is the GRE version of what now is the WS1040, but the knob configuration (squelch & volume stacked together) is the same as your WS1065.
Are you using the original telescoping antenna? Or a different one? If using an external antenna, like a roof mount), your coax might be bad. If you are
not using the original telescoping antenna, try changing to it. If you have a totally different antenna that is not currently being used, try it as well.
I double-checked the file, and it matches what the database shows. I do see one frequency licensed to the county that is not shown in the database:
156.0225 on
WREW650
However, that is not licensed as a repeater, only as a base with mobiles on the same frequency.
I don't see any new licenses for the county or Yoakum, so it does not appear that they changed frequencies. That's why I suggested that you check the squelch as well as the antenna and see if you then start hearing your local agencies. As your city (Yoakum) straddles the Lavaca/Dewitt county line, I took a look at that county to see if there was a difference for the city. On the Dewitt page, the PD frequency, 155.2500, is labeled as "encryption being used" and only shows the digital frequency on that page; the analog version of 155.2500, which is on the Lavaca page, is not listed on Dewitt.
