@kervinchong: FMD2 is working well, and the fork is from the same dev as in FMD .
The change is very simple:
you need to choose which version of FMD you need to install e.g. 32 or 64
1. Create a backup of your old fmd folder for safety
2. download the converter and modules.txt from https://github.com/dazedcat19/FMD2/releases/tag/2.0.21.0
3. put both files in your old fmd and run the converter
4. Install FMD2 (don't use your existing fmd folder !)
5. copy the content of the converted folder into your new FMD2 folder
6. start the new fmd2 once, update the modules
7. if necessary adjust small things like e.g. mangadex password inside FMD2
8. have fun
If it doesn't work delete both folders, use the backup copy and try again
hope this helps and the 3d party haters are not so angry
