Issue related to TuneAero Gen - Sorry for posting here!

[fayeackceypa83]

Hi! I really apologize for posting my issue here, but I wasn't able to in the tuneaero repo.
Anyways, I came across your tuneaero/tuneblade gen on github and tried running it. Tuneblade works great! But tuneaero gen seems to be having some problems, " startIndex cannot be larger than length of string.", seems like its regexing an empty string (combinedKey)? Am i doing something wrong here to gen a tuneaero key? Would appreciate any help, thank you!
