QuickBooks "accountants copy" extract

Apologies if this is a stupid question to all you QuickBooks experts - I barely know the package, being more of a Sage person!  In any case, this is payback for all the questions I have answered in the past!

Client has QuickBooks 2008.  When at the client's premises, I first took a "normal backup" of the data and then an "accountants copy" extract.  Since I didn't really know which one I required, I thought I'd take both to be on the safe side.

However, unknown to me, taking the accountants copy locks the client from reconciling the bank any further until the accountants adjustments have been restored.

I see we have QuickBooks 2006 and 2010 in the office and have been able to restore the backed up data and extract the bookkeeping reports required.  However, I'm reluctant to do any accountants adjustments on QuickBooks 2010 (using this accountants copy extract thingy) and then try and restore it on my client's QuickBook 2008 (if indeed that is possibly), just in case it screws the whole thing up.

Is there some function within my client's QuickBooks 2008 that can simply switch off the flag that the accountant's copy extract was taken and then she can go back to reconciling her bank account.  As far as opening balances are concerned, I'd rather just pop over there, sit in front of the company and enter them there and then, rather than do it in any more sophisticated way than that.

Thanks in advance.
