Campaign xml issues

[jehster1]

So I installed FGU on my laptop (already have a copy on my desktop) and tried to copy over my campaign folder basically using ctrl C,V. Now when I start it on both computers I get an error that says:

[6/23/2020 8:37:49 PM] FGU: v4.0.0 ULTIMATE (2020-06-19)
[6/23/2020 8:37:49 PM] OS: Windows 10 (10.0.0) 64bit
[6/23/2020 8:37:49 PM] GRAPHICS: NVIDIA GeForce GTX 1080 Ti : 11127
[6/23/2020 8:37:49 PM] USER: (redacted)
[6/23/2020 8:37:49 PM] Launcher scene starting.
[6/23/2020 8:37:49 PM] [<color="red">ERROR</color>] Owned Campaign List XML: Error loading XML file (C:/Users/Charlie's PC/AppData/Roaming/SmiteWorks/Fantasy Grounds/campaigns/Incorporated Adventures) (campaign.xml): '.', hexadecimal value 0x00, is an invalid character. Line 1, position 1.

Does anyone know the fix for this?

welcome jehster1

create a new blank 5E campaign and then close FGU
copy the campaign.xml from the new campaign over the copied campaign
copy ONLY THE CAMPAIGN.XML

always keep backups
