#177 Subscript used on non-accessible variable

[Anonymous]

We are using Dropit 8.5.1 64 bit. We are monitoring 1 folder and have two rules set up. One to ignore a specific extension, and another to upload any file with a specific extension to an ftp site. Starting a few days ago, we began receiving Line 52121 (File "C:\Program Files\DropIt\DropIt.exe"):
Error: Subscript used on non-accessible variable errors. Normally Dropit will upload a file or two, then throw the error and stop. A work around when this happens is to copy the files out of the monitored folder and copy them back to the monitored folder to get them to upload. Sometimes I must do this one file at a time, or Dropit throws the error.
