insurance

I have a wag aero sport trainer that meets all of the sport pilot rules, I
have a commercial SEL,glider Rating and a motor glider endorsement .I have
elected to exercise my privalege as a sport pilot and fly with a drivers
license. the problem is liability insurance,I have a current policy with
Avemco,however ,they don't seem to know what the company policy is and will
not commit to renewing the policy, I'm still waiting on AOPA,has anyone
else been faced with this probem.
Thanks
Ray
