XLSread error started?

I keep getting this error

Error using xlsread (line 260)
Invoke Error, Dispatch Exception:
Source: Microsoft Excel
Description: Open method of Workbooks class failed
Help File: xlmain11.chm
Help Context ID: 0

The script worked before, I changed a few values in my excel file and now I've got this error every time.

Any ideas why?

I've tried clearing the COM ADD INs in excel, restarted my PC a few times, made sure no other programs are running the same time as matlab, my file is directly in the working directory so it isn't a file path problem, any other ideas?

It's very frustrating!

Hi Walter, Thank you for the response!

I came to my PC this morning and ran my script to find that it now works... I haven;t changed anything since last night other than restart my PC, which I also tried yesterday.

Very strange, I'm now hoping it doesn't break randomly again!
