Success at last! I tried upgrading to 9.5 after I had done a clean install of my OS and the upgrade went through. Presumably the fault was on my side, but I'm not sure what, as too much has changed with the clean install to narrow it down to a single programme or add-on.

Thanks once again to Cristin, Robert and Chris for your help.

Thanks for your replies.

Cristin and Robert, I checked my Houdini License Administrator just to make sure that I did upgrade from 9.0 to 9.1 - it says Houdini Apprentice-HD 9.1 plus 2 non-commercial 9.1 licenses (Render and Master), which looks OK to me.

Chris, I have just tried to upgrade again as follows:

- using my credit card and using my husband's (both have been used successfully for online purchases in the last two or three days)
- using my computer and using my husband's (we have different security software and setups on our computers, but both computers are behind the same router and firewall).
- I also tried putting in Alaska in the state / province field in case leaving it blank was causing a problem. (A blank state field or non-US postal code or telephone format have occasionally caused problems on other sites).
- I tried on Firefox, Opera and IE7 last time, in case the new security features in Firefox 3 & Opera 9.5 were causing problems.

Unfortunately, I still get the same PSI-0403 error mentioned in my first post.

Other thoughts:

I save all passwords and licenses to an encrypted AI Roboform database as soon as I create / get them, so I don't usually have password problems. Just to check though, I presume my password is correct as I upgraded from 9.0 to 9.1 successfully and your store web page updates to reflect a $69 price once I put in the password.

I shall be installing two new hard drives and doing a clean install of Windows XP today, so I shall try to upgrade once my computer is up again, in case something on my side is preventing the transfer of information from Sidefx to PSIgate.

Thanks once again for your help

Thanks, Cristin. There is no rush at all.

When I first joined here in November, I read somewhere that the upgrade discount for Apprentice HD would only be available for a limited time after a new Houdini version was brought out, and I didn't want to lose the discount.
