Pastel V18 Bank Manager Error

[pwentzel88]

Hi everyone. I downloaded and installed Pastel V18 and everything seems to be working perfectly. Well, everything except the Bank Manager.
When I click on the "Pastel Bank Manager" button on the bottom of the Cash Books screen, it loads for a few seconds, and then I get an error saying : "Error. Value cannot be null. Parameter name : source". When I click OK it takes me to a blank Statement Review screen. If I then click on the "import file" option, it again gives me the same error.

Please help!
