There are two possible ways I can think of going about this if reaching out to owner isn't a possibility

1)  See if you can decompile the project and debug/fix the issue.
2) You can run a pcap and find the call being made out, you could add a hostfile entry to repoint the request to a machine you control and simply spit back the answer you need.

Fair warning though, this feels like the tip of the iceberg, I imagine this is due to you receiving an error from a server rather than actual values, as per Driz before.  If that's the case, it might be easier to just find a replacement app to achieve the same goal.

I don't have the source code and I will try the second option.

How hard would it be to just find a replacement app? I suspect you might be entering a very long and tedious process to resolve this?
