[Plugin: NextGEN Gallery] Conflict with Contact Form 7 plugin

I have Contact Form 7 installed version 3.2. When i upgraded it appears to cause a problem with NextGEN Gallery plugin version Version 1.9.3.

The error is when trying to upload a photo into a gallery. The error is the same as above.

As above, the images does not upload.

1. How do I go back to the previous version of Contact From 7?
2. How long does it normally take to have something like this fixed?

Thank you

Just discovered this this morning and had to disable CF7, really hope it gets fixed soon

Following.

I reverted to a previous version of CF7 and this straightened out the problem for me:
