我试图通过Tortoise SVN Checkout选项下载开放式牙科13.1版开发人员代码，但每次都会出现以下错误。
Failed to run the WC DB work queue associated with
'F:\OpenDentalwc\Macros\ConversionMacro', work item 62 (file-install
Macros/ConversionMacro/ConversionMacro.vsmacros 1 0 1 1)
Can't open file
'F:\OpenDentalwc\.svn\pristine\71\71535ffbcdaaa8fc84a5e75f7449efcde47ce8e1.svn-base':
Access is denied.
需要一些帮助才能通过Tortoise SVN下载Open Dental代码。
