Just got a BCD536HP from a fellow ham. The scanner works fine but I can't get sentinel to work. I tried installing the version on the SD card and the version downloaded from your site. I always get an error that talks about a file mismatch. It also says that it can't find the database on the C: drive. The database seems OK on the SD card because it uses it in scanning. The SD card is seen as my G: drive. I really need Sentinel to work because it's a big hassle to use only the radio for that. I also can't do a firmware upgrade or upgrade the database. Please help me. I can follow a procedure because I used to work in IT. Thank you.
