Tiny Umbrella Error ?

I have an Ipad2 and was told the latest version of Tiny Umbrella can read and save the SHSH files for me, I am running Win7 64 Bit and all other version work but the latest 4.30.05 when I run it I get error 16 "An internal Error Occured" I have download it from a few sources now ? has anyone run into this before ? All other version run but when I try and use version 4.30.00 the Ipad2 shows in TU but just had a large black ? beside it

Any ideas

Thanks
