Going from MF6 TBYB to MF6 regular (not Plus)

[MaxAlien]

I've been using the TBYB version of MF6 on Vista 32-bit and now it's expired. I liked the program and I'd like to buy the regular version of it, not the Plus version, since I won't be creating HD DVDs. I created two projects on the TBYB version which I'd like to keep burning DVDs from. Can I do that with the regular version, or do I have to get the Plus version, since the TBYB version is essentially Plus?
