HN: Anyone else offered a GRE Retest?

Today I received a letter from ETS stating that I can retest the verbal part of the GRE. They say that the testing algorithms were not optimized. Considering that I only scored a 590 on the verbal, I have thought about taking it again. Has anyone else experienced a similar situation? Did your score increase? I honestly thought I was just good at math and was terrible at English.
