There are 2 issues in your inimoneyinfo.ini
1. The file encoding is BOM+UTF-8. you will not read the [section]. you need to save as UTF-8 or ANSI encoding
2.The PromptPayID =123456789 makes the key "PromptPayID " it has a space, you will not get the value of PromptPayID. you need to remove the space front of =.
