I can do checkouts, update and such. But when I try to commit changes, SVN gives me the following error:
Can't open file '/svn/p/pokemonium/code/db/txn-current-lock': Permission denied
I am using Windows 7 x64 SP1 with latest version of TortoiseSVN. UAC is off, my account has read and write access, etc.
I can commit fine to other svn repositorys.
Try this.
This will leave you (hopefully) with a working copy that shows (!) on all the files you had modified since your last commit. And fixes your lock issue.
