After 10+ years with VDSP and multiple PC, I'm out of license. What to do ?

Hi,

there is up 4 PC on the same license but after using it for 10+ years, I'm at my 5th PC and now I can't validate my license.

Any options ?

Currently using v4.5 update 9 to compile and v5.1.1 (for debugging with ICE-100).

Thanks
