Hello westbros   As Nick has pointed out Your User name could in fact be the cause of this    But Changing the actual name for your folder directory is a bit tricky,   This would involve you creating another User account and removing your old account.   The alternative is also a bit messy,  You could add another User account to Windows 10 (Standard account)   Prepar3D would still be in place no problem,  But you would need to download and Install FTX Central again,
