Sorry to hear you wish to cancel. I have removed all renewals on your software, so you will no longer be charged.
It does need to be noted here, you are unfortunately venting frustration in the wrong direction. No matter what software you use, you will get that very same error when trying to write temp files. That error being mentioned is not coming from our software in any way. It's coming directly from the operating system on your server. Unfortunately there physically no way for us, as the software company, to resolve this.
I would mention here, if you do decide you wish to move forward again in the future, our cloud solution may well be a better fit for you. It would mean you do not have to worry about the hosting at all, as that is all managed on your behalf
